I used to have a whitelist for specific sites but some spam set the from
and to address to the destination site site and so can bypass bogofilter.I
have now removed the whitelist and just use bogofilter.

Current performance for my account:

Version 0.9
Method robinson
Default settings
"Honeytrap" feeding my spamlist.db
Spam training messages 1400
Ham training messages 620

Spam received 774
False negatives 11
False positives 0

So the false negative rate is about 1.4%
and the false positive rate is < 0.2%
