Had a similar situation a while back.  Instead of blocking my secondary, I
used the access table in it's sendmail to drop inbound connections from the
offending IP.  That way, I could continue to receive valid email on the
secondary from elsewhere but not plug the queues with virus laden emails.  I
had the advantage, of course, of owning our secondary.

Do you have shell access to the secondary?  If not, I'd try to get your ISP
to block that address.

I also notified the sender's ISP so they could notify the owner of the
infected machine.

Good luck...
