Installing SA-Exim4 may be too invasive, though. :(

FWIW, what I do is:

- - we don't have an MTA-level spam filter... for various reasons. :(
  so similar to the lugh situation.

- - use MailMan 2.1.x  (MUCH better).   I see lugh is already running
  this.

- - allow "posting only from subscriber addresses" in MailMan

- - all subscriber posts are passed through immediately.

- - the nagmails for non-subscriber posts will arrive at the moderator
  list.  Have SEVERAL people on this list.

- - These mails are now much better designed than they were in 2.0.x:
  they contain commands which will block/unblock/permanently unblock
  that sender.  So here's a good script:

      http://jmason.org/software/scripts/moderate-list.txt

  this goes through an MH/Maildir-style folder and will remember list
  passwords, block and unblock members and postings, in a relatively more
  useful interactive-cmdline interface than the crappy MM admindb
  interface.

- - Finally, for the ones that get forgotten, Ronan Waide wrote a good
  script which scrapes the admindb interface, runs the mails through
  SpamAssassin, and deletes the "this is spam" ones.  Coupled with
  a bayes DB trained to recognise viruses as spam ;)  this works
  well, too.

  (I have some hack^Wadditions to this script that I really need to feed
   back to waider at some stage.)

FWIW, making sure that members can post freely helps a lot; the members
(the day to day community) are not impeded at all.
