Looks like we stopped receiving email like 9 days ago

Which caused our bounce notifications not to come through and lead to issues with Amazon SES. I am trying to understand why POP3 is not receiving email, it is configured correctly as far as I can tell and the account appears to be working ok I can connect externally etc

Any ideas welcome.

Thanks!

Ram through this

The response was nill if I entered everything correctly and got an error if I put in the wrong password so it seems fine.

Grasping at straws

How many emails do you see, if you connect with a mail-client ?

In my case, I disabled deleting old messages and got timeouts with too many mails in the queue.
After moving processed mails to an archive, the timeouts disappeared.
