MailScanner on Red Hat 8.0 and Exchange

Even though I do get the relay message with your test below, I added the
local W2K domain name of our windows domain and it has not stopped
sending mail as of yet and it has been 10 minutes whereas before I added
that domain into the sendmail relay files, I would get errors pretty
much right away. So, it seems it was sendmail giving the relay error and
I may have nipped it in the bud now.



ps. I can see in the log that it is checking for viruses too.
