Problems with Exchange 2003

lynnfennell · 10-23-2009, 03:14 PM

We recently took an old Exchange to a different server. We host our own exchange. Our internet is through Comcast. Everything is fine internally we receive and send messages on outlook. We are also receiving internet mail. But all our outgoing internet messages are stuck in a retry queue. We get a delayed message then a failure.

hey there
have you had any issues with DNS?? make sure that the email server is got the correct DNS server, and make sure that the DNS server has a place to forward all of the unmatched queries, if you need specific instructions let me know

Comcast, like many ISP's, blocks port 25 for foreign SMPT servers. Try adding their SMTP server as a Smarthost in your SMTP connector. Basically your server will relay outgoing mail to the smarthost.

hello lynnfennell......or another good suggestion and pretty reasonable cost is to try a SMTP relay provider, dnsexit.com is pretty reliable. I've never had any issues with our outgoing emails using dnsexit.com our our SMTP relay. We have the same issue with our AT&T Provider, in your case it's Comcast.
