Howdy, All,
Running cPanel 62.0 (build 16), CentOS 7.3 x64, on a KVM VPS. 4 Cores and 10 Gigs memory, usually don't go above .25 load and three gigs memory in use. The system is not under heavy load.
Have ConfigServer's MailScanner installed (they did the installation).
Have a particular email address that's an alias to several users (around a dozen).
Have not made any config changes recently.
Every now and again a message to the alias will not be delivered.
Can see the inbound connection in /var/log/exim_mainlog, but don't see the delivery to each user.
In /var/log/maillog, normally as soon as Mailscanner logs to MailWatch SQL, I'll see dovecot "Connect from local", then an entry for each user in the group showing the message saved to their INBOX.
But when they fail, there's no record in maillog that dovecot connected and performed the actual delivery.
Am not sure exactly where to look, as the problem is intermittent. Everything seems to always work up to the point where MailScanner logs the message. Not sure why dovecot doesn't always kick in to deliver.
Since there's plenty of memory and cpu available, if it's a setting I should bump up it wouldn't be a problem.
Any ideas why this might be happening, and more importantly, how to fix it?
Thanks!
