Email Problems

Anyone having email accounts that just suddenly stopped working today (this evening)? I have 4 or 5 domains that the email has been working fine, went out for couple of hours and now email accounts not running. Sent in a ticket and was told the accounts are not running email services but they have been. Some for quite a few years now.

Just wondering if anyone else is having issues like this.
