The SMTP log wasn’t enabled to see the logs.
We have Exchange 2003 which is connected to Exchange 2007 on the same domain. We are migrating all the mailboxes from Exchange 2003 to 2007 and the “Routing Group Connector” is connecting from 2003 to 2007 using SmartHost
So is it only mail being sent from mailboxes that are still on Exchange 2003 that are having this issue?
this was the same message that I got in exchange 2003 last time.
this was because the email cannot go out as the DNS was removed from the server and was looping inside the server.
This is most probably a dns issue or a firewall issue(depends on if any rules changes),
What you can do is test with a simple telnet from your Source to Destinations exchange server and vice versa, because for some reason the mail is not leaving the queue,
What can also happen is that when you got a corrupted mail in the queue is messes up the queue, what AV are you using for mail scanning Mcafee Groupshield etc?Maybe its not running and in the process not removing the corrupted item/items,
Hope this helps,
Regards
