[ipac] Spam problems from our HIP server

[Rex Cornelius]

I have seen this also, from more than one mail account I manage here.
I assumed the spammer used us for a spoofed return address and ignored
it... we had only a handful.  I would think that if your mailer were
being used, that would mean it had been cracked and was being used as
a relay - something you could check by looking for massive changes in
the outgoing message count, no?

Any experts on mailer trojans on the list?
