There're +/- one hour delayed...

I don't see any for understand what it's the problem.

Possible LOAD? Cron jobs?

Have you checked the server during the time(s) when the messages aren't automatically delivering to see what is happening?

You might also check the mailman logs at /usr/local/cpanel/3rdparty/mailman/logs/error during those time(s) to see if any errors are indicated. The other logs there that might be helpful are qrunner and smtp-failure ones.
