Hello,

I need to point my single Exchange 2007 server to an external relay.
I have the IP address, but I am not exactly sure how to setup the send connector.

I added a send connector pointing to the DNS name to be routed to, using MX records option selected. This then left me with two send connectors, I disabled the original one and now when I send out a test mail, I get:

Last Error: A matching connector cannot be found to route the external recipient
Queue ID: LAV-EXCH\Unreachable
Recipients:  check-auth@verifier.port25.com

I know Im missing something here... :)

Thanks!

Check your send connector.

First make sure under Address Space it's set to *

Then under Network select Route mail through the following smart host.  And enter the IP address of your relay server.

I added the DNS name to be routed to for the smarthost. and used * as the address space.

No error now, but messages just sit in the queue as "Ready"

can you telnet to the hostname on port 25 from the exchange server?

Yes and I could successfully send a message, while connected, from my domain.

Check the source server is set in the last tab of the send connector?

Also restart the Microsoft Exchange Transport service.

Under send connectors, I now have two. Should the old one be disabled?

Existing:
ADDRESS SPACE: type/SMTP address space/* cost/1 - scoped send connector: unchecked
NETWORK: Use DNS/MX to route mail/checked

New:
ADDRESS SPACE: type/SMTP address space/* cost/1 - scoped send connector: unchecked
NETWORK: Smart Host: FQDN (tested with telnet) - Use external DNS lookup setting is unchecked

The source server is the same on existing/working as well as the new one. That part should be good

I will try again and restart the service, but my question at this point is do I leave the existing send connector and the new one enabled at the same time? I would guess not...

Thanks!
