FAQ: Mail service EXIM currently down?

Is EXIM mail service currently down?

We haven’t received any official reports stating that our EXIM mail service is down. EXIM is part of our managed infrastructure, and any system-wide outages would be communicated on our status page or via email. To verify:

• Check the IP ServerOne status page for any alerts.
• See if you’ve received any service-wide notices or notifications from our team.
• If you’re experiencing outgoing or incoming delivery failures, it might be a local issue on your server.

How to troubleshoot if EXIM appears down on your server

Here are the key checks and actions to take:

1. Verify the EXIM process is running
   Connect to your server via SSH and run:
   ps aux | grep exim
   If it’s not running, restart it with:
   sudo service exim restart
2. Check SMTP ports are listening
   Use netstat or ss:
   netstat -lnp | grep exim
   Ensure ports 25, 465, 587 are configured in daemon_smtp_ports = 25 : 465 : 587.
3. Review EXIM log files
   Check /var/log/exim/mainlog and /var/log/exim/paniclog.
4. Look for SMTP errors or throttling
   Watch for errors like 421 Too many concurrent SMTP connections.
5. Check firewall or port blocking
   Ensure SMTP ports aren’t blocked—both locally and by your provider.
