We are doing something like this for the local (campus) Debian group. We have some generic filtering which drops obvious spam and viruses. Subscriber mail goes through, as does anything coming from an on-campus account (and some other frequent-posters-but-not-subscribed). Everything else gets moderated. The big question with this is how willing our mailing list administrators are to do this once-a-day manual filtering. (Rik has mentioned that they already do some spam filtering, but linux-crypto seems to get quite a bit of spam anyways.) -- Hubert Chan <hubert@xxxxxxxxx> - http://www.uhoreg.ca/ PGP/GnuPG key: 1024D/124B61FA Fingerprint: 96C5 012F 5F74 A5F7 1FF7 5291 AF29 C719 124B 61FA Key available at wwwkeys.pgp.net.
