I've got vpopmail/netqmail built using typical clamav and spamassassin
(clamd, spamd). I've got XBL filtering and CHKUSER enabled on smtp. I'm
actively training my Bayes filters. I do not use verified sender or SPF.
Spamassassin's local.cf look like this:
rewrite_header Subject [SPAM]
score RCVD_IN_BL_SPAMCOP_NET 2
I STILL find a good bit of spam is getting through. (pharma, mortgages,
stock hype, etc)
I wonder whether there are other/better anti-spam tools I should use to
cull the spam more effectively. Suggestions most welcome.
