We recently added a new Exchange Server (2003) to our
Exchange 2003 organization. Our Internet Mail Connector is still on our
original mail server and we added the new server as a bridgehead server to this
Internet Mail Connector. The users that have mailboxes hosted on the new
Exchange server can send e-mail outbound to the internet without trouble with
the exception of two domains so far. They are aol.com and Comcast.net.
It appears from headers that I have looked at that the accounts
being hosted on the new e-mail server are going directly out to the internet
from the new box with SMTP and not going through the Internet Mail Connector on
our original mail server. I had thought that all internet bound (outbound)
e-mail would route through the IMC on the original mail server, but I was
incorrect.
For those mailboxes that are still on the original Exchange
server, e-mailing aol.com and Comcast.net isn’t an issue.
Any thoughts or advice?
Thanks,
