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.
