Mail received but server sends back '5.4.7 Delivery expired' mesage
Hello!
I've "inherited" an Exchange 2013 server that for the last month, even tho it receives mail, it sends back to outside senders a message like this, after a few days:
Action: failed
Status: 5.0.0 (permanent failure)
Diagnostic-Code: smtp; 5.4.7 - Delivery expired (message too old) 'timeout' (delivery attempts: 0)
Some details I know about the setup:
-there's a Cisco Ironport email filter for outside mail - tech support on that said it's not at fault
-exchange server was upgraded from 2010 to 2013. The old server and connectors still appear in the settings.
-there might be an issue with the exchange server seeing the secondary domain controller as the primary but this is an old issue and might not be related
-get-messagetrackinglog mentions HAREDIRECTFAIL and SEND events for external received email (there's only one server so I don't know why Transport high availability is on)
-mxtoolbox.com doesn't report any problems with my email domain
I would love to know if you have any ideas as to why this is happening!
Thank you!
