I've been using bogofilter too. I have about 15,000 messages
of junk mail divided up into spam/scam/virus/bogus delivery messages.
I trained bogofilter on my spam and ham (ham being all
my archived mailing list mail and personal mail archives)
The results were ok. I got far too many false positives.
The main false positives were mail from myself at work
with a single web site link -- I mail myself interesting
links to read. So these look pretty spammy, although
I obviously need a whitelist.
I really dislike false positives, and I don't see how
bayesian analysis can avoid them. I'm always going to
have the occasionally valid but spammy look mail.
As unfortunate as it is, I think the only way to combat
spam is to make it expensive to send by default.
Expensive here means more expensive than a good return
return by the spammers. Say the spammers get a hit rate
of selling $100 worth of stuff for every million messages,
then the cost of sending mail should be at least double
that rate -- it should cost them about $200 to send a million
Is there any mail client that integrates tightly with
spam detectors? I'd like to click on a column to sort
messages by spamicity.
