exchange 2010 email stuck in queue
Posted on 2013-06-28
I moved a test user to a new 2010 server. Yesterday I set up connectors and was able to send and receive email internally and externally. However, today all emails from the test user are getting stuck in the queue. I am able to still receive emails.
Now, I do have two 2010 servers configured. I only set up the firewall for one email server (.5). The properties of the stuck emails show that the source IP is .15, which is the other email server. I am not sure why today emails are trying to be sent from that server. The .15 server is going to be a passive DAG server. I realize I may need to configure the firewall for that specific IP address, but I am unclear why it is trying to send out through it when yesterday it sent exclusively through the .5 server.
Another thing is that my 2003 server is configured to send out through the 2010 server and that is working without issue.
thanks for any insight.
