 		    GNU GENERAL PUBLIC LICENSE
 		       Version 2, June 1991
 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 			    Preamble
  The licenses for most software are designed to take away your
 freedom to share and change it.  By contrast, the GNU General Public
 License is intended to guarantee your freedom to share and change free
 software--to make sure the software is free for all its users.  This
 General Public License applies to most of the Free Software
 Foundation's software and to any other program whose authors commit to
 using it.  (Some other Free Software Foundation software is covered by
 the GNU Lesser General Public License instead.)  You can apply it to
 your programs, too.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 this service if you wish), that you receive source code or can get it
 if you want it, that you can change the software or use pieces of it
 in new free programs; and that you know you can do these things.
  To protect your rights, we need to make restrictions that forbid
 anyone to deny you these rights or to ask you to surrender the rights.
 These restrictions translate to certain responsibilities for you if you
 distribute copies of the software, or if you modify it.
  For example, if you distribute copies of such a program, whether
 gratis or for a fee, you must give the recipients all the rights that
 you have.  You must make sure that they, too, receive or can get the
 source code.  And you must show them these terms so they know their
 rights.
  We protect your rights with two steps: (1) copyright the software, and
 (2) offer you this license which gives you legal permission to copy,
 distribute and/or modify the software.
  Also, for each author's protection and ours, we want to make certain
 that everyone understands that there is no warranty for this free
 software.  If the software is modified by someone else and passed on, we
 want its recipients to know that what they have is not the original, so
 that any problems introduced by others will not reflect on the original
 authors' reputations.
  Finally, any free program is threatened constantly by software
 patents.  We wish to avoid the danger that redistributors of a free
 program will individually obtain patent licenses, in effect making the
 program proprietary.  To prevent this, we have made it clear that any
 patent must be licensed for everyone's free use or not licensed at all.
  The precise terms and conditions for copying, distribution and
 modification follow.
 		    GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  0. This License applies to any program or other work which contains
 a notice placed by the copyright holder saying it may be distributed
 under the terms of this General Public License.  The "Program", below,
 refers to any such program or work, and a "work based on the Program"
 means either the Program or any derivative work under copyright law:
 that is to say, a work containing the Program or a portion of it,
 either verbatim or with modifications and/or translated into another
 language.  (Hereinafter, translation is included without limitation in
 the term "modification".)  Each licensee is addressed as "you".
 Activities other than copying, distribution and modification are not
 covered by this License; they are outside its scope.  The act of
 running the Program is not restricted, and the output from the Program
 is covered only if its contents constitute a work based on the
 Program (independent of having been made by running the Program).
 Whether that is true depends on what the Program does.
  1. You may copy and distribute verbatim copies of the Program's
 source code as you receive it, in any medium, provided that you
 conspicuously and appropriately publish on each copy an appropriate
 copyright notice and disclaimer of warranty; keep intact all the
 notices that refer to this License and to the absence of any warranty;
 and give any other recipients of the Program a copy of this License
 along with the Program.
 You may charge a fee for the physical act of transferring a copy, and
 you may at your option offer warranty protection in exchange for a fee.
  2. You may modify your copy or copies of the Program or any portion
 of it, thus forming a work based on the Program, and copy and
 distribute such modifications or work under the terms of Section 1
 above, provided that you also meet all of these conditions:
    a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.
    b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.
    c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)
 These requirements apply to the modified work as a whole.  If
 identifiable sections of that work are not derived from the Program,
 and can be reasonably considered independent and separate works in
 themselves, then this License, and its terms, do not apply to those
 sections when you distribute them as separate works.  But when you
 distribute the same sections as part of a whole which is a work based
 on the Program, the distribution of the whole must be on the terms of
 this License, whose permissions for other licensees extend to the
 entire whole, and thus to each and every part regardless of who wrote it.
 Thus, it is not the intent of this section to claim rights or contest
 your rights to work written entirely by you; rather, the intent is to
 exercise the right to control the distribution of derivative or
 collective works based on the Program.
 In addition, mere aggregation of another work not based on the Program
 with the Program (or with a work based on the Program) on a volume of
 a storage or distribution medium does not bring the other work under
 the scope of this License.
  3. You may copy and distribute the Program (or a work based on it,
 under Section 2) in object code or executable form under the terms of
 Sections 1 and 2 above provided that you also do one of the following:
    a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,
    b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,
    c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)
 The source code for a work means the preferred form of the work for
 making modifications to it.  For an executable work, complete source
 code means all the source code for all modules it contains, plus any
 associated interface definition files, plus the scripts used to
 control compilation and installation of the executable.  However, as a
 special exception, the source code distributed need not include
 anything that is normally distributed (in either source or binary
 form) with the major components (compiler, kernel, and so on) of the
 operating system on which the executable runs, unless that component
 itself accompanies the executable.
 If distribution of executable or object code is made by offering
 access to copy from a designated place, then offering equivalent
 access to copy the source code from the same place counts as
 distribution of the source code, even though third parties are not
 compelled to copy the source along with the object code.
  4. You may not copy, modify, sublicense, or distribute the Program
 except as expressly provided under this License.  Any attempt
 otherwise to copy, modify, sublicense or distribute the Program is
 void, and will automatically terminate your rights under this License.
 However, parties who have received copies, or rights, from you under
 this License will not have their licenses terminated so long as such
 parties remain in full compliance.
  5. You are not required to accept this License, since you have not
 signed it.  However, nothing else grants you permission to modify or
 distribute the Program or its derivative works.  These actions are
 prohibited by law if you do not accept this License.  Therefore, by
 modifying or distributing the Program (or any work based on the
 Program), you indicate your acceptance of this License to do so, and
 all its terms and conditions for copying, distributing or modifying
 the Program or works based on it.
  6. Each time you redistribute the Program (or any work based on the
 Program), the recipient automatically receives a license from the
 original licensor to copy, distribute or modify the Program subject to
 these terms and conditions.  You may not impose any further
 restrictions on the recipients' exercise of the rights granted herein.
 You are not responsible for enforcing compliance by third parties to
 this License.
  7. If, as a consequence of a court judgment or allegation of patent
 infringement or for any other reason (not limited to patent issues),
 conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot
 distribute so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you
 may not distribute the Program at all.  For example, if a patent
 license would not permit royalty-free redistribution of the Program by
 all those who receive copies directly or indirectly through you, then
 the only way you could satisfy both it and this License would be to
 refrain entirely from distribution of the Program.
 If any portion of this section is held invalid or unenforceable under
 any particular circumstance, the balance of the section is intended to
 apply and the section as a whole is intended to apply in other
 circumstances.
 It is not the purpose of this section to induce you to infringe any
 patents or other property right claims or to contest validity of any
 such claims; this section has the sole purpose of protecting the
 integrity of the free software distribution system, which is
 implemented by public license practices.  Many people have made
 generous contributions to the wide range of software distributed
 through that system in reliance on consistent application of that
 system; it is up to the author/donor to decide if he or she is willing
 to distribute software through any other system and a licensee cannot
 impose that choice.
 This section is intended to make thoroughly clear what is believed to
 be a consequence of the rest of this License.
  8. If the distribution and/or use of the Program is restricted in
 certain countries either by patents or by copyrighted interfaces, the
 original copyright holder who places the Program under this License
 may add an explicit geographical distribution limitation excluding
 those countries, so that distribution is permitted only in or among
 countries not thus excluded.  In such case, this License incorporates
 the limitation as if written in the body of this License.
  9. The Free Software Foundation may publish revised and/or new versions
 of the General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
 Each version is given a distinguishing version number.  If the Program
 specifies a version number of this License which applies to it and "any
 later version", you have the option of following the terms and conditions
 either of that version or of any later version published by the Free
 Software Foundation.  If the Program does not specify a version number of
 this License, you may choose any version ever published by the Free Software
 Foundation.
  10. If you wish to incorporate parts of the Program into other free
 programs whose distribution conditions are different, write to the author
 to ask for permission.  For software which is copyrighted by the Free
 Software Foundation, write to the Free Software Foundation; we sometimes
 make exceptions for this.  Our decision will be guided by the two goals
 of preserving the free status of all derivatives of our free software and
 of promoting the sharing and reuse of software generally.
 			    NO WARRANTY
  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
 REPAIR OR CORRECTION.
  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
 POSSIBILITY OF SUCH DAMAGES.
 		     END OF TERMS AND CONDITIONS
 	    How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 convey the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>
    Copyright (C) <year>  <name of author>
    This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.
    This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.
    You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
 Also add information on how to contact you by electronic and paper mail.
 If the program is interactive, make it output a short notice like this
 when it starts in an interactive mode:
    Gnomovision version 69, Copyright (C) year name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate
 parts of the General Public License.  Of course, the commands you use may
 be called something other than `show w' and `show c'; they could even be
 mouse-clicks or menu items--whatever suits your program.
 You should also get your employer (if you work as a programmer) or your
 school, if any, to sign a "copyright disclaimer" for the program, if
 necessary.  Here is a sample; alter the names:
  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  `Gnomovision' (which makes passes at compilers) written by James Hacker.
  <signature of Ty Coon>, 1 April 1989
  Ty Coon, President of Vice
 This General Public License does not permit incorporating your program into
 proprietary programs.  If your program is a subroutine library, you may
 consider it more useful to permit linking proprietary applications with the
 library.  If this is what you want to do, use the GNU Lesser General
 Public License instead of this License.

 ## Class decorator to enable optional protocol steps.
 # P_SKIP is enabled by default when supported, but
 # applications may wish to enable P_HDR_LEADSPC
 # to send and receive the leading space of header continuation
 # lines unchanged, and/or P_RCPT_REJ to have recipients 
 # detected as invalid by the MTA passed to the envcrpt callback.
 #
 # Applications may want to check whether the protocol is actually
 # supported by the MTA in use.  Base._protocol
 # is a bitmask of protocol options negotiated.  So,
 # for instance, if <code>self._protocol & Milter.P_RCPT_REJ</code>
 # is true, then that feature was successfully negotiated with the MTA
 # and the application will see recipients the MTA has flagged as invalid.
 # 
 # Sample use:
 # <pre>
 # class myMilter(Milter.Base):
 #   def envrcpt(self,to,*params):
 #     return Milter.CONTINUE
 # myMilter = Milter.enable_protocols(myMilter,Milter.P_RCPT_REJ)
 # </pre>
 # @since 0.9.3
 # @param klass the %milter application class to modify
 # @param mask a bitmask of protocol steps to enable

 # by the MTA.  Use like this with python-2.6 and later:
 # <pre>
 # @@Milter.rejected_recipients
 # class myMilter(Milter.Base):
 #   def envrcpt(self,to,*params):
 #     return Milter.CONTINUE

 # @param klass the %milter application class to modify
 # @return the modified %milter class
 def rejected_recipients(klass):

 ## Milter leading space on headers. A class decorator that calls
 # enable_protocols() with the P_HDR_LEADSPC flag.  By default,
 # header continuation lines are collected and joined before getting
 # sent to a milter.  Headers modified or added by the milter are
 # folded by the MTA as necessary according to its own standards.
 # With this flag, header continuation lines are preserved
 # with their newlines and leading space.  In addition, header folding
 # done by the milter is preserved as well.
 # Use like this with python-2.6 and later:
 # <pre>
 # @@Milter.header_leading_space

 # another %milter and wants to disable a callback again.
 # The disabled method should still return Milter.CONTINUE, in case the MTA does
 # not support protocol negotiation, and for when called from a test harness.

 ## Function decorator to set decoding error strategy.
 # Current RFCs define UTF-8 as the standard encoding for SMTP
 # envelope and header fields.  By default, Milter.Base decodes 
 # envelope and header values with errors='surrogateescape'.
 # Applications can recover the original bytes with 
 # <pre>
 # b = s.encode(errors='surrogateescape')
 # </pre>
 # This preserves information, but can lead to unexpected exceptions
 # as you cannot, e.g. print strings with surrogates.
 # Illegal bytes occur quite often in real life, so there must
 # be a way to deal with them.
 # This decorator can change the error strategy to
 # <ul>
 # <li> bytes    - original bytes are passed unmodified
 # <li> strict   - pass bytes if illegal bytes are present, string otherwise
 # <li> ignore   - illegal bytes are removed
 # <li> replace  - illegal bytes are replaced with a unicode error symbol

 ## A do "nothing" Milter base class representing an SMTP connection.
 #
 # Python milters should derive from this class
 # unless they are using the low level milter module directly.  
 #
 # Most of the methods are either "actions" or "callbacks".  Callbacks
 # are invoked by the MTA at certain points in the SMTP protocol.  For
 # instance when the HELO command is seen, the MTA calls the helo
 # callback before returning a response code.  All callbacks must
 # return one of these constants: CONTINUE, TEMPFAIL, REJECT, ACCEPT,
 # DISCARD, SKIP.  The NOREPLY response is supplied automatically by
 # the @@noreply decorator if negotiation with the MTA is successful.
 # @@noreply and @@nocallback methods should return CONTINUE for two reasons:
 # the MTA may not support negotiation, and the class may be running in a test
 # harness.
 # 
 # Optional callbacks are disabled with the @@nocallback decorator, and
 # automatically reenabled when overridden.  Disabled callbacks should
 # still return CONTINUE for testing and MTAs that do not support
 # negotiation.  
 # Each SMTP connection to the MTA calls the factory method you provide to
 # create an instance derived from this class.  This is typically the
 # constructor for a class derived from Base.  The _setctx() method attaches
 # the instance to the low level milter.milterContext object.  When the SMTP
 # connection terminates, the close callback is called, the low level connection
 # object is destroyed, and this normally causes instances of this class to be
 # garbage collected as well.  The close() method should release any global
 # resources held by instances.
 # @since 0.9.2

    # The <code>Milter.CURR_ACTS</code> bitmask is all actions

 ## @package Milter.dsn
 # Support DSNs and CallBackValidations (CBV).
 #
 # A Delivery Status Notification (bounce) is sent to the envelope
 # sender (original MAIL FROM) with a null MAIL FROM (<>) to notify the
 # original sender # of delays or problems with delivery.  A Callback Validation
 # starts the DSN process, but stops before issuing the DATA command.  The
 # purpose is to check whether the envelope recipient is accepted (and is
 # therefore a valid email).  The null MAIL FROM tells the remote
 # MTA to never reply according to RFC2821 (but some braindead MTAs
 # reply anyway, of course).
 #
 # Milters should cache CBV results and should avoid sending DSNs
 # unless the sender is authenticated somehow (e.g. SPF Pass).  However,
 # when email is quarantined, and is not known to be a forgery, sending a DSN 
 # is better than silently disappearing, and a DSN is better than sending
 # a normal message as notification - because MAIL FROM signing schemes
 # can reject bounces of forged emails.   Whatever you do, don't copy those
 # assinine commercial filters that send a normal message to notify you
 # that some virus is forging your email.
 #
 # <b>DSNs should *only* be sent to MAIL FROM addresses.</b>  Never send
 # a DSN or use a null MAIL FROM with an email address obtained from
 # anywhere else.

 # Abstract
 This is a python extension module to enable python scripts to attach to
 Sendmail's libmilter API, enabling filtering of messages as they arrive.
 Since it's a script, you can do anything you want to the message - screen
 out viruses, collect statistics, add or modify headers, etc.  You can, at
 any point, tell Sendmail to reject, discard, or accept the message.
 Additional python modules provide for navigating and modifying MIME parts, and
 sending DSNs or doing CBVs.
 # Requirements 
 Python milter extension: https://pypi.org/project/pymilter/
 Python: http://www.python.org
 Sendmail: http://www.sendmail.org
   or
 Postfix: http://www.postfix.org/MILTER_README.html
 # Quick Installation
 1. Build and install Sendmail, enabling libmilter (see libmilter/README).
 2. Build and install Python, enabling threading.
 3. Install this module: python setup.py --help
 4. Add these two lines to sendmail.cf[a]:
 ```
 O InputMailFilters=pythonfilter
 Xpythonfilter,        S=local:/home/username/pythonsock
 ```
 5. Run the sample.py example milter with: python sample.py
 Note that milters should almost certainly not run as root.
 That's it.  Incoming mail will cause the milter to print some things, and
 some email will be rejected (see the "header" method).  Edit and play.  
 See spfmilter.py for a functional SPF milter, or see bms.py for an complex
 milter used in production.
 [a] This is for a quick test.  Your sendmail.cf in most distros will get
 overwritten whenever sendmail.mc is updated.  To make a milter permanent,
 add something like:
 ```
 INPUT_MAIL_FILTER(`pythonfilter', `S=local:/home/username/pythonsock, F=T, T=C:5m;S:20s;R:5m;E:5m')
 ```
 to sendmail.mc instead.
 # Not-so-quick Installation
 First install Sendmail.  Make sure you read libmilter/README in the Sendmail
 source directory, and make sure you enable libmilter before you build.  The
 8.11 series had libmilter marked as FFR (For Future Release); 8.12
 officially supports libmilter, but it's still not built by default.
 Install Python, and enable threading in Modules/Setup.
 Install this miltermodule package; DistUtils Automatic Installation:
 $ python setup.py --help
 Now that everything is installed, we need to tell sendmail that we're going
 to filter incoming email.  Add lines similar to the following to
 sendmail.cf:
 ```
 O InputMailFilters=pythonfilter
 Xpythonfilter,        S=local:/home/username/pythonsock
 ```
 The "O" line tells sendmail which filters to use in what order; here we're
 telling sendmail to use the filter named "pythonfilter".
 The next line, the "X" line (for "eXternal"), lists that filter along with
 some options associated with it.  In this case, we have the "S" option, which
 names the socket that sendmail will use to communicate with this particular
 milter.  This milter's socket is a unix-domain socket in the filesystem.
 See libmilter/README for the definitive list of options.
 NB: The name is specified in two places: here, in sendmail's cf file, and
 in the milter itself.  Make sure the two match.
 NB: The above lines can be added in your .mc file with this line:
 ```
 INPUT_MAIL_FILTER(`pythonfilter', `S=local:/home/username/pythonsock')
 ```
 For versions of sendmail prior to 8.12, you will need to enable
 `_FFR_MILTER` for the cf macros.  For example,
 ```
 m4 -D_FFR_MILTER ../m4/cf.m4 myconfig.mc > myconfig.cf
 ```
 # IPv6 Notes
 The IPv6 protocol is supported if your operation system supports it
 and if sendmail was compiled with IPv6 support.  To determine if your
 sendmail supports IPv6, run "sendmail -d0" and check for the NETINET6
 compilation option.  To compile sendmail with IPv6 support, add this
 declaration to your site.config.m4 before building it:
 ```
 APPENDDEF(`confENVDEF', `-DNETINET6=1')
 ```
 IPv6 support can show up in two places; the communications socket
 between the milter and sendmail processes and in the host address
 argument to the connect() callback method.
 For sendmail to be able to accept IPv6 SMTP sessions, you must
 configure the daemon to listen on an IPv6 port.  Furthermore if you
 want to allow both IPv4 and IPv6 connections, some operating systems
 will require that each listens to different port numbers.  For an
 IPv6-only setup, your sendmail configuration should contain a line
 similar to (first line is for sendmail.mc, second is sendmail.cf):
 ```
 DAEMON_OPTIONS(`Name=MTA-v6, Family=inet6, Modify=C, Port=25')
 O DaemonPortOptions=Name=MTA-v6, Family=inet6, Modify=C, Port=25
 ```
 To allow sendmail and the milter process to communicate with each
 other over IPv6, you may use the "inet6" socket name prefix, as in:
 ```
 Xpythonfilter,        S=inet6:1234@fec0:0:0:7::5c
 ```
 The connect() callback method in the milter class will pass the
 IPv6-specific information in the 'hostaddr' argument as a tuple.  Note
 that the type of this value is dependent upon the protocol family, and
 is not compatible with IPv4 connections.  Therefore you should always
 check the family argument before attempting to use the hostaddr
 argument.  A quick example showing this follows:
 ```
  import socket
  class ipv6awareMilter(Milter.Milter):
     def connect(self,hostname,family,hostaddr):
 	if family==socket.AF_INET:
 	   ipaddress, port = hostaddr
 	elif family==socket.AF_INET6:
 	   ip6address, port, flowinfo, scopeid = hostaddr
 	elif family==socket.AF_UNIX:
 	   socketpath = hostaddr
 ```
 The hostname argument is always safe to use without interpreting the
 protocol family.  For IPv6 connections for which the hostname can not
 be determined the hostname will appear similar to the string
 "[IPv6:::1]" with the corresponding hostaddr[0] being "::1".  Refer to
 RFC 2553 for information on interpreting and using the flowinfo and
 scopeid socket attributes, both of which are integers.
 # Authors
 Jim Niemira (urmane@urmane.org) wrote the original C module and some quick
 and dirty python to use it.  Stuart D. Gathman (stuart@gathman.org) took that
 kludge and added threading and context objects to it, wrote a proper OO
 wrapper (Milter.py) that handles attachments, did lots of testing, packaged
 it with distutils, and generally transformed it from a quick hack to a
 real, usable Python extension.

 ## @mainpage Writing Milters in Python
 #
 # At the lowest level, the <code>milter</code> module provides a thin wrapper
 # around the <a href="milter_api/index.html"> sendmail
 # libmilter API</a>.  This API lets you register callbacks for a number of
 # events in the process of sendmail receiving a message via SMTP.  These
 # events include the initial connection from a MTA, the envelope sender and
 # recipients, the top level mail headers, and the message body.  There are
 # options to mangle all of these components of the message as it passes through
 # the %milter.
 # 
 # At the next level, the <code>Milter</code> module (note the case difference)
 # provides a Python friendly object oriented wrapper for the low level API.  To
 # use the Milter module, an application registers a 'factory' to create an
 # object for each connection from a MTA to sendmail.  These connection objects
 # must provide methods corresponding to the libmilter event callbacks.
 # 
 # Each callback method returns a code to tell sendmail whether to proceed with
 # processing the message.  This is a big advantage of milters over other mail
 # filtering systems.  Unwanted mail can be stopped in its tracks at the
 # earliest possible point.  The callback return codes are
 # milter.CONTINUE, milter.REJECT, milter.DISCARD, milter.ACCEPT, 
 # milter.TEMPFAIL, milter.SKIP, milter.NOREPLY.
 # 
 # The Milter.Base class provides default implementations for
 # event methods that do nothing, and also provides wrappers for the libmilter
 # methods to mutate the message.  It automatically negotiates with MTA
 # which protocol steps need to be processed by the %milter, based on
 # which callback methods are overridden.
 #
 # The Milter.Milter class provides an alternate default
 # implementation that logs the main milter callbacks, but otherwise does
 # nothing.  It is provided for compatibility.
 # 
 # The mime module provides a wrapper for the Python email package
 # that fixes some bugs, and simplifies modifying selected parts of a MIME
 # message.
 #
 # @section threading
 #
 # The libmilter library which pymilter wraps 
 # <a href="milter_overview#SignalHandling">handles
 # all signals</a> itself, and expects to be called from a single main thread.
 # It handles SIGTERM, SIGHUP, and SIGINT, mapping the first two to 
 # <a href="milter_api/smfi_stop.html">smfi_stop</a>
 # and the last to an internal ABORT.
 #
 # If you use python threads or threading modules, then signal handling gets
 # confused.  Threads may still be useful, but you may need to provide an
 # alternate means of causing graceful shutdown.
 #
 # You may find the
 # <a href="http://docs.python.org/release/2.6.6/library/multiprocessing.html">
 # multiprocessing</a> module useful.  It can be a drop-in
 # replacement for threading as illustrated in 
 # <a href="milter-template_8py-example.html">milter-template.py</a>.
 #
 # @section Useful python packages for milters
 #
 # <a href="https://github.com/sdgathman/pymilter">pymilter</a> - this package.
 #
 # <a href="https://github.com/sdgathman/pyspf">pyspf</a> checks the
 # SMTP envelope sender (MAIL FROM, passed to the Milter.Base.envfrom callback)
 # against a Sender Policy published in DNS by the sending domain.  This
 # can prevent forgery of the MAIL FROM.  SPF is Sender Policy Framework.
 #
 # <a href="https://launchpad.net/dkimpy">pydkim</a> checks a DKIM signature
 # of the email body and headers against a public key published in DNS by
 # the signing domain.  DKIM is DomainKeys Identified Mail.
 #
 # The <a href="https://pypi.python.org/pypi/authres/">authres</a> module 
 # parses and formats the Authentication-Results email header, providing
 # a standard place to summarize the results from DKIM, SPF, rDNS, SMTP AUTH,
 # and other email authentication methods.
 #
 # <a href="https://github.com/sdgathman/pydspam/">pydspam</a> wraps 
 # the libdspam API of the <a href="http://dspam.sourceforge.net/">DSPAM</a>
 # project.
 #
 # <a href="https://github.com/sdgathman/pysrs/">pysrs</a> rewrites
 # MAIL FROM to include a timestamped signature so that "bounce spam"

 ## @package milter
 #
 # A thin wrapper around libmilter.  Most users will not import
 # milter directly, but will instead import Milter and subclass
 # Milter.Base.  This module gives you ultimate low level control
 # from python.
 #
 ## Continue processing the current connection, message, or recipient.
 CONTINUE  = 0
 ##  For a connection-oriented routine, reject this connection; 
 # call Milter.Base.close(). For a message-oriented routine, except
 # Milter.Base.eom() or Milter.Base.abort(), reject this message.  For a
 # recipient-oriented routine, reject the current recipient (but continue
 # processing the current message).
 REJECT    = 1
 ## For a message- or recipient-oriented routine, accept this message, but
 # silently discard it.  SMFIS_DISCARD should not be returned by a
 # connection-oriented routine.
 DISCARD   = 2
 ## For a connection-oriented routine, accept this connection without further
 # filter processing; call Milter.Base.close().   For a message- or
 # recipient-oriented routine, accept this message without further filtering.
 ACCEPT    = 3
 ## Return a temporary failure, i.e., the corresponding SMTP command will return
 # an appropriate 4xx status code. For a message-oriented routine, except
 # Milter.Base.envfrom(), fail for this message.  For a connection-oriented
 # routine, fail for this connection; call Milter.Base.close().  For a recipient-oriented
 # routine, only
 # fail for the current recipient; continue message processing.
 TEMPFAIL  = 4
 ## Skip further callbacks of the same type in this transaction. 
 # Currently this return value is only allowed in Milter.Base.body(). It can be
 # used if a %milter has received sufficiently many body chunks to make a
 # decision, but still wants to invoke message modification functions that are
 # only allowed to be called from Milter.Base.eom(). Note: the %milter must
 # negotiate this behavior with the MTA, i.e., it must check whether the
 # protocol action SMFIP_SKIP is available and if so, the %milter must request
 # it.
 SKIP      = 5
 ## Do not send a reply back to the MTA. 
 # The %milter must negotiate this behavior with the MTA, i.e., it must check
 # whether the appropriate protocol action P_NR_* is available and if so,
 # the %milter must request it. If you set the P_NR_* protocol action for a
 # callback, that callback must always reply with NOREPLY. Using any other
 # reply code is a violation of the API. If in some cases your callback may
 # return another value (e.g., due to some resource shortages), then you must
 # not set P_NR_* and you must use CONTINUE as the default return
 # code. (Alternatively you can try to delay reporting the problem to a later
 # callback for which P_NR_* is not set.)
 #
 # This is negotiated and returned automatically by the Milter.noreply 
 # function decorator.
 NOREPLY   = 6
 ## Hold context for a %milter connection.
 # Each connection to sendmail creates a new <code>SMFICTX</code> struct within
 # libmilter.  The milter module in turn creates a milterContext
 # tied to the <code>SMFICTX</code> struct via <code>smfi_setpriv</code>
 # to hold a PyThreadState and a user defined Python object for the connection.
 # 
 # Most application interaction with libmilter takes places via 
 # the milterContext object for the connection.  It is passed to
 # callback functions as the first parameter.
 #
 # The <code>Milter</code> module creates a python class for each connection,
 # and converts function callbacks to instance method invocations.

 # We also provide workarounds for bugs in the email module that comes

 Cleo - please review attached feedback from Sales team.......I recall at 
 an early meeting after we moved in you and Tony (and maybe 1 or 2 
 others) were going to develop a voice mail procedure or instruction 
 sheet for all staff. It looks like we really need this to get what we 
 are looking for from the system. Please let me know when you can produce 
 this and give a draft to the managers here for review.
 Thanks,
 Lee

 Rich:
 Following is a summary of concerns from customers regarding internal
 communications within WS:
 	- Not all employees have activated their voice mail - when this is the
 case, the system will automatically cut you off
 	- When employees are out of the office, phones are not forwarded to a back
 up, ie manager
 	- Reception has no record of employee attendance, and therefore will
 forward call to individual requested - see point 2
 	- Reception directs calls to incorrect individuals
 	- When entering voice mail, if you press '0', system does not default to
 operator, but puts you back into individual 	voice mail
 	- Reception phone demeanor has no 'pep'
 Thanks
 Joe
