You may wish to consider ACLs for this stuff.
In particular exiscan-acl might be very helpful.
http://article.gmane.org/gmane.mail.exim.exiscan.user/354
and the rest of that thread discusses a possible hack to allow
different virus-check settings for different users.
You could use a wrapper script which runs different filtering
apps depending on the recipient (perhasp by passing the user
on the command line).
This was very experimental at the time it was discussed (mid March
this year).
One other point to watch with this hack - if you don't listen for
SMTP, but download and inject from POP/IMAP/batch SMTP/...
the injecting application is unlikely to retry (on a later occasion)
address that give temporary errors.
