We continue to receive reports of continued problems from a very few clients.
We essentially addressed the problem on the evening (UTC) of 19 March. We have yet to put in place a permanent fix. The permanent fix is to attach a secondary volume, and move some back-ups onto the secondary volume, to free up space on the primary hard drive to store and process email. We have not done this yet.
However, we have freed up a huge amount of space, so the server is comfortably handling all the email thrown at it. This is the temporary fix.
The reported problems seem to focus on two areas:
- Bounced email, and
- Expected but not received emails.
We have been working on the mail server non-stop for about 21 hour now. We have rebooted the server once (in the morning UTC) and restarted applications a few times. During that time foreign mail servers may have been disconnected in the middle of trying to deliver an email, resulting in their bouncing the email with an error that refers to “losing the connection while receiving the initial server greeting”. Given how often this would have happened (not very much) we’re surprised to see this bounce, but it’s obviously happened. We can only expect these events to lessen as things return to normal.
We ourselves have noticed that emails from external/foreign sources have not been arriving lately. We can only expect that these emails are delayed, and we expect to receive them again in the next 24 hours. Please be patient.
If you check your domain at mxtoolbox.com you will find that it should comply with all or most requirement to have your email delivered. Not complying with every requirement is not necessarily a bad thing.
We expect to have the permanent fix in place within the next 12 hours, but the temporary fix is more than enough to keep the email flowing. Thank-you.
