What percentage of emails using your algorithm are actually

Almost 100% if you look at a wide variety of tokens from multiple
attributes. Subject, body, content flags, header structure, combinations
of all domains reference, php scripts, name part of from addresses,
behavior flags.
I would have said that a very large number of the words used in spam mails are
the same as the words used in ham mails, so I suspect I'm confused about what
constitutes a "token".
The ones that are the same are of no interest. Only where it matches one
side and not the other.
I fail to see how the "name part of from addresses" are unlikely to match ham,
for example, since I see quite a lot of spam apparently from myself.
Antony.
Some spammers have Viagra in the name part. The name part is very
spammy. I also store to and from email addresses so that relationships
between people corresponding create a ham result. (I filter outbound as
well for some people)
