Category: list administration Group: Mailman 2.0.x Status: Open Resolution: None Priority: 5 Submitted By: James Henstridge (jhenstridge) Assigned to: Nobody/Anonymous (nobody) Summary: Add SpamAssassin filter to mail pipeline

Initial Comment: This filter adds support for discarding or holding spam sent to the mailing list. It contacts a spamd daemon (from SpamAssassin -- http://spamassassin.taint.org) to score the message.

If the score is above a certain threshold (default 10), the message is discarded and an entry is written to the vette log.

If the score is above another lower threshold (default 5), the message is held for moderation.

The SpamAssassin.py file should be installed in Mailman/Handlers/. The LIST_PIPELINE variable in Mailman/Handlers/HandlerAPI.py should be modified to include a 'SpamAssassin' item (I put it just after the existing 'SpamDetect' item).

To change the defaults, the following can be added to the mm_cfg.py file: SPAMASSASSIN_HOST = 'host:port' # how to contact SA SPAMASSASSIN_DISCARD_SCORE = 10 SPAMASSASSIN_HOLD_SCORE = 5

If you don't want to discard messages, then DISCARD_SCORE can be set to something very high (1000 should do it).

It looks the MM2.1 filter APIs have changed a bit, so this filter will need some modifications to work with that version. When I get round to upgrading, I might look into updating it.

This version is essentially the same as the previous version, but adds compatibility with python > 1.5.2, which doesn't like you passing two arguments to socket.connect().

Just attached my updated version of the patch. This version requires SpamAssassin 2.20 (for the extra commands that the spamd daemon understands). It now displays a list of which rules were triggered for held messages, and can give messages from list members a bonus (defaults to 2), so that they are less likely to get held as spam.

There is a fairly easy optimisation for this filter that I missed when writing it. It calls str() on the message object twice. It would be quicker to call str() on the message once.
