I have a really strange IMC issue that I am hopeful someone here can shed
some light on.
Our company routes mail for multiple domain names. In our corporate office
we have 2 Exchange servers each in their own site. Our corporate server
(Exch 5.5 Sp4) hosts mail for 3 domain names, and the other (Exch 5.5 Sp3)
hosts a single domain name. The external DNS records for all our domain
names point to virtual hosts on our Raptor firewall which re-directs the
mail into the appropriate Exchange server. The IMCs on both servers have
routing restrictions to only accept the appropriate e-mail addresses.
What I am trying to accomplish is to collapse the single domain server into
the larger corporate server. However, the corporate server is un-willing to
accept the domain's e-mail even though it's been added to the routing list.
It bounces with a 550 Domain Invalid message.
If I turn on logging on the IMC I see the following:
8/26/2001 4:26:02 PM : A connection was accepted from firewall.company.com.
8/26/2001 4:26:02 PM : <<< IO: |HELO firewall.company.com
|
8/26/2001 4:26:02 PM : <<< HELO firewall.company.com
8/26/2001 4:26:02 PM : >>> 250 OK
8/26/2001 4:26:02 PM : <<< IO: |MAIL FROM:<[EMAIL PROTECTED]>
|
8/26/2001 4:26:02 PM : <<< MAIL FROM:< [EMAIL PROTECTED]>
8/26/2001 4:26:02 PM : >>> 250 OK - mail from < [EMAIL PROTECTED]>
8/26/2001 4:26:02 PM : <<< IO: |RSET
|
8/26/2001 4:26:02 PM : <<< RSET
8/26/2001 4:26:02 PM : >>> 250 OK - Reset
8/26/2001 4:26:03 PM : <<< IO: |QUIT
|
8/26/2001 4:26:03 PM : <<< QUIT
8/26/2001 4:26:03 PM : >>> 221 closing connection
I do not have hotmail on a restricted list, and this process works just fine
if I point the firewall back to the original Exchange server. I have moved
the 2nd Exchange server into the same site as the corporate server, as well
as deleted and re-created the IMC on the corporate server, all with no
effect.
I am completely at a loss as to why this server will not accept this one
domain name. Any insights any one has, or ideas as to where else to look for
clues would be greatly appreciated.
