I have an exchange 5.5 sp4 server that appears to be
relaying mail. I've looked up information on preventing
Exchange 5.5 from being an open relay and configured it
accordingly. I've tested it with abuse.net manually
through telent and it says it's not an open relay, but
when I look at the outgoing mail queue in the IMS there is
a bunch of mail in there that is definitely not business
related. The ones that are still in the queue are there
because of being host unreachable. I don't know how many
are acutally going through. Does anybody have any
suggestions?
