hi all!
i have one exchange server 5.5 with sp5. this server connects to a mail
relay where webshield smtp is installed and where all mail from/to the
outside world comes/goes.
today i received a message from other mail server (external) like this:
"Message REJECTED due to incorrect configuration of YOUR mail server. Your
mail server is incorrectly configured and this has caused your mail to be
rejected. Reject Reason: HELO greeting is incorrect: 504 need
fully-qualified hostname. The name which your mail server uses to identify
itself is NOT a Fully Qualified Domain Name (FQDN) resolvable by the DNS
and thus we have rejected your message. To ensure that mail sent to our
mail server arrives correctly please ensure your configuration is
correct."
this never happened before (at least, i have no knowledge of anything
similar ever happened) and nothing was changed in the config of the
exchange server or the mail relay.
ok... my question is: where do i configure this? can someone help?
thanks a lot
