Erm, find a UNIX host to act as your mail server and run SpamAssassin
there.
http://www.csoft.net/ where I host my website and send email to have
Spam Assassin available, and some simple tinkering with .forward
(.qmail in this case) pipes all mail through Spam Assassin.
They also have Perl with various Mail:: modules too, so I've actually
got a fair amount of email processing happening server side, before I
even get fetchmail on the case.
Once I've got my email locally, it gets injected into my local qmail
install and through Spam Assassin again, but with tighter rules.
If all you have is a simple POP3/IMAP account, then you'll need to
knock something together to filter as you download the messages or
just use headers/partial messages to decide if you fetch each message.
Cheers,
Baz.
