If you changed your MX record externally, it could take up to 48 hours
to propagate through the internet.  If you have an internal DNS MX
record pointing to your mail server at the publishing ip or fqdn, you
should be okay.  Sometimes, patience is all it takes.  Watching the mail
queue won't make it send and receive any faster.  The tutorial on this
site is excellent.  Is your mail server on the same box as the ISA
server? This could be causing problems also?

Frank,

I'm not an expert in Mail Server, but I can give you some tips.

First off all, your Mail Server have to be an SNat client and Not an
Firewall Client.
To do this, remove your Firewall Client from that server and configure
the
Defaut Gatway properly.

Second, you have to put fixes IP's at yours servers (not DHCP Clients).
When you have this, you can Publish your Mail server at ISA by it's own
mailserver IP, and you don't have to worrie about your DNS internal to
receive Mails.

You told that you can send Mails ok. Then yours DNS configurations are
ok
to OUT. Now, you have to chek if you have an Host and an MX entry at
your
DNS external pointing to your ISA external interface.

I got some good information about it at learning zone from Shinder.

Thank you
