Everything was working fine on my server for the last six months. no changes have been made on the server or router.
In the morning we stop receiving emails, I restarted the server and we started to receive emails .
2 hours we stop getting emails. I have looked at the logs and dont see any failures.
don't understand why we cant get email from the outside. we get emails from inside the domain through Blaberry and Iphone but no other emails.
