Also, when one telnets to this host, not only is the unusual message given,
but the remote host immediately disconnects. So no mail can be delivered.
BTW, that IP is found on the domain name, and IMail should use that ONLY
after using the MX records (which point to a different server that does not
refuse the connections!). You log should show IMail attempting the host in
the MX records first, with a 'MX fail connect', if it cannot connect. If you
do not see this, then something else (DNS or name resolution (HOSTS file?)
related?) is not giving IMail the MX records that I see when I check DNS.

have an unusually high level of spam detection (checking reverse DNS on the
IP address), but it sounds like they have something misconfigured. Either
way, their welcome message is wrong (the reason for not allowing the
connection is NOT because it doesn't accept relaying -- it doesn't know at
that point if you are sending a local or remote E-mail).
