I've actually noticed this as well. The first 6 months or so Spamassassin has been a dreem. I'd estimate nearly 99% of spam was tagged. Now four or five are slipping through a day. The only thing I can suggest (and what I have been doing) is to feed the misses back through SA's bayesian engine. It's a little time consuming but it helps SA "learn" what the spammers are up to. I have to agree with your theory though, I think spammers are just trying out new techniques and SA hasn't caught up yet. - -b -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQFAF9unmNhQdx6oCWoRAumZAKCtiT0rnvPdT5v8p9F4bDmo5hahjQCeNDbz tyDU8PVZ+27/LGirxHa09AI= =S+CA -----END PGP SIGNATURE----- -- [EMAIL PROTECTED] mailing list
