Hi I really need some help with this. We have been running zimbra without a problem for the last year or so. Today I started to get complaints that we were not being received or sent (no error messages, emails just never arrived).
I took a look at the email queues and I had 6000 deffered, 4000 incoming and about 20000 active.
I have stopped postfix, and blocked all access to the zimbra server at the firewall level.
I really need help in determining my next steps.
Thanks in advance...
