Question : Exchange 2003 FQDN AD Question

I have an exchange 2003 server that has been running super.  However, I recently have had some issues with mails going out (recipient server barks that the FQDN does not match...).  After opening exchange and going into the properties (SMTP), I see that the FQDN listed is the local computer account name.

My question is this:
If I change the FQDN domain name in the exchange SMTP properties to the "real" FQDN, is that going to create major issues as it will not match the AD domain name?

Will inserting a Masquar. domain in that box solve this issue?

Thoughts?

No that's not the problem.  Enter it into the FQDN box, The problem is that many postmaster out there require that the fqdn that your mailserver sends out resolves to the ip of your mailserver.

So basicly whatever the dns name is which points to the public ip (or the ip your mail server is natted out through) of your mailserver. Put that in the FQDN

They are asking for the FQDN of the mailserver in this box so it should not create any problems regarding the Active directory domain

Or

Setting the Smart host to the smtp server of your ISP will also solve the problem....


Hope you can use any of this info to solve your problem.
