Steve is your Exim installation set up to reject mail on spamminess,
using SpamAssassin or similar?

I find that SA detects a lot of mail using SA rules that probably
contain attachments or inline images that are virus laden, but it's
cheaper on system resources to reject at SMTP time than running ClamAV
on every mail received.
