I noticed that all emails stay in the queue for about 10 minutes and as soon as a new mail arrives in the queue the age is 23:00 hours.
I removed the outgoing mail control restrictions and there is no greylisting functionality enabled. I switched back and forth from postfix to qmail
but it didn't fix the problem. By the way qmail worked fine. I also checked the log files but there was nothing obvious to me. Any suggestions?
