emails sent from server do not reach my company mailbox

[zappo0305]

I have an issue with one of my server whereby the alert emails sent from the internal server do not reach my internal/company mailbox.

However, I've tested with an external recipient (a gmail address) and the emails are received without problems

The sending address of my server is: srv1-test12@[11.11.11.11]

I've added the sender verification exceptions but still no go.

Looking at the message tracking,  the message is queued for delivery and eventually get expired with the following error message:

Double bounce: Message 24019xxxx to srv1-test12@[11.11.11.11]. Reason: 5.4.7 - Delivery expired (message too old) 'timeout'

Im new to ironport and I dont know what else to check. Thanks in advance for your feedback.

Hi zappo0305,

Please check if you have an SMTP route entry for domain "[11.11.11.11]" pointing to your internal MTA. If you dont have it, I would recommend adding this entry in your SMTP Routes by:

GUI -> Network -> SMTP Routes -> Add Route
