When configuring my Exchange 2003 SMTP virtual server, what do I use for the FQDN under the advanced delivery section. Do I use our domain.com or mail.domain.com... Here is how it is setup:
MX record for domain.com is mail.domain.com
PTR for IP points to mail.domain.com
A record exists for mail.domain.com
I'm assuming that I put mail.domain.com in there and that is what I have been using... However we have been having some outgoing email issues and I want to make sure that part is correct. Thanks...
