Comment 15 for bug 266588

Attached is an updated version of the filter for adding
SpamAssassin support to mailman. This version is targetted
at Mailman 2.1.x.

The code for talking to spamd has been split out into a
separate file, so that it can be updated independently of
the Mailman specific code. It has also been updated to work
with SpamAssassin 2.50 (and should be a lot more robust to
future additions to the spamd protocol).

The filter has also been changed to use the list name as the
username passed to spamd, which means that separate
auto-whitelists and bayes databases can be maintained for
each list.

Installation is trivial. Simply copy spamd.py and
SpamAssassin.py to the Mailman/Handlers directory and add
the following line to Mailman/mm_cfg.py:
  GLOBAL_PIPELINE.insert(1, 'SpamAssassin')
