 # 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)

 ## 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

 # 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.

 ## @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"
 # can be immediately rejected.
 #
 # <a href="https://github.com/sdgathman/pygossip/">pygossip</a> is a

 # 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

 ## 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.
