Multiple Domains + mail server host greeting name
Morning!
I have an Exchange Server 2003 which hosts 2 email domains (@domainA.com & @domainB.com).
DomainA is our company's email account and DomainB is our hosted companies email account. I had a feeling this would happen, when I did a DNS REPORT on it I received a warning that the "mail server host greeting name" is not mis-representing itself, i.e., the greeting host is showing as DomainA's MX record. I have the proper MX records, mail.domainA.com & mail.domainB.com including proper r-dns records. Can you "fudge" exchange so that it properly reports both MX records in the mail greeting host??
TIA,
Steve

Came across this recently in a group I'm a part of... not sure if it's what you're looking for:
Under the SMTP Connector go under Properties and on one of those tabs there is an Advanced button revealing a field where you can change the name to mail.yourcustomer.com

Thanks for your responses.
It seems as though I have the server created correctly with proper RDNS and MX records. I was worried that outbound email from DOMAINB would have issues with some mail servers if it was responding with a mail server greeting name of DOMAINA.
Per DIEPES last reponse, that's the exact configuration I have now.
Please let me know if you have any other thoughts - thanks!

you can read up on SPF sender policy frame work, that is a way to add dns records for domainA and domainB that appoints your mail server as a legitimate sender for both of these domain.
But is is not used/checked widely by mail servers.

It seems that your Exchange Server is Internet Front.
You should install a SMTP gateway between Internet and your Exchange server (eq. Linux with Postfix) and modify the MX (on Internet) for all domains you host to point to your SMTP gateway.
