Hi

I have been having the same problem as on thread

http://www.zimbra.com/forums/showthread.php?t=989

This is where mail gets stuck in the mail queue.

If the following is done

zmcontrol stop
zmcontrol start
postqueue -f

This almost always flushes the queue.

However this is not neat and I want a better work around until the other thread has identified the core problem.

I have used M1 and it was OK and I made the mistake of going live with M2
so I am manually running the process above every 30 minutes.

I would much rather

1) Stop postfix
2) Start postfix
3) Flush the queue

Then automate this in a cron job.

How do we stop and start postfix in the zimbra environment, do we need to be logged in as zimbra or root?

I know this is not the solution to the problem, but all hell breaks loose when I
forget to not run the manual flush.

Help please

John
