Hi folks,
We do not have open relay on our two Exchange servers (5.5 SP4) as tested by
various tools. However in the queue of IMC, there are thousand of messages
that have outside domains in both source and destination addresses. The
addresses of originators are obviously computer generated
or three days. The server had shut down because
the drive ran out of space.
So I clear that up and start nosing around..
I check for open relay (telnet), and can't find any problem. I start to think maybe
this is a SoBig.F issue, until I read some of the NDRs.
