    Hello,
    My dedicated server hosting provider is using a monitoring service for various services one of which is SMTP. As of yesterday's Cpanel update WHM 11.52.0 (build 15) the monitoring is reporting that SMTP is down even though it isn't.

    After inspecting the exim_mainlog I can see that:
    Until yesterday monitoring SMTP connections where closed like:
    2015-10-14 21:32:45 SMTP connection from [95.154.xxx.xxx]:56365 (TCP/IP connection count = 1)
    2015-10-14 21:32:45 no host name found for IP address 95.154.xxx.xxx
    2015-10-14 21:32:45 SMTP connection from [95.154.xxx.xxx]:56365 closed by QUIT

    and from today they are like:
    2015-10-15 22:26:15 SMTP connection from [95.154.xxx.xxx]:63373 (TCP/IP connection count = 1)
    2015-10-15 22:26:15 no host name found for IP address 95.154.xxx.xxx
    2015-10-15 22:26:25 SMTP connection from [95.154.xxx.xxx]:63373 lost

    Looking at the updates that run overnight, I went from 11.50.2.2 to 11.52.0.15 - could you please advise what could be the change that affect the way the monitoring connection is getting lost?

    I hope you'll be able to help
    Thanks in advance.

    This is covered in the release notes and just needs an timeout adjustment: 11.52 Release Notes - Documentation - cPanel Documentation

    Thank you Penguin.
    As I don't have access to the monitoring system to configure it I have now added the monitoring systems IP to the whitelist. The exact location for the whitelist is:
    "Exim Configuration Manager > Basic > Access Lists > Trusted SMTP IP addresses"

    Thanks for your response I can mark this Solved!
