There is no provision that I know of in fetchmail to filter stuff before
it downloads it, but you could have exim4 filter it before it gets to
your mailbox.

My setup rejects both viruses and spam by scanning the message at the
DATA stage of the SMTP conversation. You need exim4-daemon-heavy with
the acl patch, clamav for virus checking and spamassassin for spam. Use
sa-learn to educate spamassassin's Bayes filter. I installed this set
up about 4 days ago and instead of deleting hundreds of spams and
viruses each day, I now have hardly any.

Can you go to someone else who will let you use SMTP to get mail? (Like
Demon Internet in the UK.)
