mail routing

[Chris Coho, Jr.]

We are having a small problem. We host our own email server on our domain.
When outside the office you can access it fine from mail.domain.com. inside
the office you can access it fine with the server name "domain1". The
problem is that when you try to access it from inside the office with
mail.domain.com it doesn't work. This is a proble because we have some
folks set up with laptops who travel and their email software is set up to
access the mail server as mail.domain.com. Does anyone have any
suggestions on how to fix this? we have a mail server and an internet
gateway server/routing server. If from any internal desktops we run a trace
on mail.domain.com it brings up our gateway ip address, not the mail server
ip address, probably because of our external mx records which point to our
internet gateway server and are then routed to the mail server when trying
to access from outside.

Any help would be appreciated

The internal DNS server must be misconfigured. Create a A type record for
mail.domain.com on it.

Either set up an internal DNS server, or use the hosts file.

thanks for the reply. ok i tried to create a host record for
mail.domain.com but it wouldn't accept the periods, so I created one for
"mail". Now i can access the mail server via mail.domain, but still not
mail.domain.com. I still think I'm doing something wrong but I'm unsure
what.

any ideas?

Got it working, my zone was set up as domain, I needed to create a new zone
in the dns called domain.com and create the host and mx records in there.

Thanks for all who assisted!!!
