Thanks for the feedback.

The "mail.hostname" vanity issue is something I've been trying to remove
from our servers -- this gives a good foundation to contiue my battle.

Thanks again.

Douglas,

There are two issues here.

First:

>www.dnsreport.com  states that "mail.thisdomain.com claims to be host
>X1."

And  it  always will, as long as you're using an Imail version through
7.x.  Imail  flouts  the  RFCs  by  putting a proprietary 'X1 NT-ESMTP
Server'  after its SMTP 220 greeting and before your primary hostname.
As  most  DNS  verifiers  parse out the first word after the 220, they
think  your  server  is  claiming  to  be  host  'X1.' The hostname is
actually the fourth word after the 220 on Imail servers.

Ipswitch  doesn't  seem  likely  to  fix  this,  since it's endemic to
Imail's peering feature--it's how Imail servers "know" each other.

Second:

>We  host  about 50 virtual domains with imail and each domain has its
>own "mail." host name listed in our name server.

As  long  as you're going to do this part, you'll never pass the test,
anyway.  Imail  can only answer as one hostname (the primary hostname)
per  IP.  If  you're setting up address records for lots of hosts that
resolve to the same IP, only one of them will pass the test.

In  sum, there's really nothing you can do to be completely compliant,
though  I  tend  to  think that the everyone-gets-their-own-branded-MX
thing  is  just  a vanity measure and you could eliminate that part to
save you the management burden. Then, if Ipswitch ever fixes the first
problem, you'd be ready.
