To follow up on my own message... the problem was greater than the
viruses alone.  The server was sending mail (likely
virus mail) with forged From addresses.  The server (which
hosts the mailing list) would respond with "450 sender domain must
resolve" (a measure to trap just such problems.  This, unfortunately,
meant that the server would continue to try sending
these messages.

It got to the point where, at times, I would receive many of these
attempts *per second* from the server.  I decided to, on
a temporary basis, permenantly reject all mail from that server to get
all these viruses out of the system.  (That ban was in place for a total
of about 5 minutes... Hopefully that will clear things up.)

I do not know why is sending these weird virus messages;
the To: line seems to be random people under the domain.
Perhaps somebody can check on that.
