|
|

|
|
0.5.2 Fix and add to unit test another parsing failure.
|
|
0.5.1 Properly handle modifications to rfc822 attachments.
|
|
Handle encoded rfc822 attachments.
|
|
0.5.0 Use config file so users don't have to keep syncing the
|
|
bms.py script. Keep bms.py marked as %config for a while
|
|
to avoid wiping out their customizations just yet.
|
|
0.4.5 Work with sgmlop package to speed up HTML parsing.
|
|
Reduce various local hacks to config variables.
|
|
0.4.4 Bug fixes for HTML encoding.
|
|
0.4.3 Handle quoted-printable HTML attachments. Remove entire
|
|
attachment when HTML can't be parsed.
|
|
0.4.2 Parse HTML attachments to remove <script ...>...</script>.
|
|
Klez virus uses malformed MIME part separators to prevent
|
|
the multifile module and other virus scanners from seeing its
|
|
HTML attachment (which contains Javascript and VBScript). Outhouse
|
|
happily accepts and executes the malformed attachments, but
|
|
we still kill the Klez virus because we:
|
|
Defang attachment when any Content-Type attribute ends with
|
|
a banned extension - one of the Outhouse bugs exploited by the
|
|
Klez virus. Outhouse really, really stinks . . .
|
|
0.4.1 Bug fix from Jason Erikson for NULL hostaddr in connect callback.
|
|
0.4.0 New check_attachments(msg,check) function in mime module allows
|
|
filtering based on attachment contents. Distribution now includes
|
|
bms.py, an example milter used in production - including use of the
|
|
new check_attachments(msg,check) API.
|
|
Report hostname in WARNING.TXT.
|
|
More parameter list bug fixes.
|
|
|
|
0.3.10 Parse quotes in parameter lists to handle embedded ';'.
|
|
Move test data to subdirectory, write non-junit output to
|
|
log file in test subdirectory.
|
|
0.3.9 Handle non-multipart messages with executable content in sample.py,
|
|
add more extensions to banned list.
|
|
0.3.8 Handle malformed Content-Type in mime.py. Test viruses have
|
|
been deactivated by deleting most of the viral code.
|
|
0.3.7 Put back hint on running sample.py. Add .bat as banned extension.
|
|
More sample spam filtering logic.
|
|
0.3.6 Ran through pychecker-0.8.5. Most systems will name the sendmail
|
|
user library (used by the milter extension module) 'libsm', but AIX
|
|
still needs to call it 'libsmutil' because there is a system library
|
|
called 'libsm'.
|
|
0.3.5 Enhanced logging. Fix bug in sample milter where headers were
|
|
included in body when removing a virus.
|
|
0.3.4 Tested distribution on RH6.2 and updated sample.py and docs.
|
|
Tested with gcc-2.95.2, python-2.1.1, sendmail-8.11.6-2.6.x
|
|
The RH6.2 spec file to enable libmilter for sendmail-8.11.6
|
|
can be obtained from http://www.bmsi.com/linux/sendmail-rhmilter.spec
|
|
The SRPM can be obtained from http://www.redhat.com
|
|
|
|
0.3.3 Remove reference to sa_len - not supported by linux.
|
|
|
|
0.3.2 Rename and add more hints to the sample milter.
|
|
|
|
0.3.1 Pass a more useful hostaddr to the connect callback.
|
|
|
|
0.3 Interface now uses a milterContext extension object instead of
|
|
an index. A PyThreadContext is now created for each milterContext so that
|
|
"simultaneously" processing multiple messages at once (as often happens
|
|
on a busy server) actually works.
|
|
|
|
Many milter methods are now object methods of the milterContext
|
|
extension object. No compatibility API is provided for this change due
|
|
to the limited user base at this stage. The setname method has been removed,
|
|
and the name is now passed to register.
|
|
|
|
A simple class to provide an OO wrapper to the milter API is
|
|
provided.
|
|
|
|
A simple class to parse multipart mime messages into parts and replace
|
|
selected parts is provided. The sample filter will eventually use the mimelib
|
|
package instead, but mimelib currently requires reading the entire message
|
|
into memory.
|
|
|
|
A sample filter that replaces attachments with naughty extensions
|
|
with a warning message is provided.
