Postfix can't run

[nye_zhang]

After a system crash, my Zimbra don't work.
When I run zmcontrol status:
Host mail.mydomain.com
antispam Running
antivirus Running
ldap Running
logger Running
mailbox Running
Timeout after 180 seconds

The last sentence won't show untile 180 seconds later.
I think it shows one of service in mta has no response.
so I run:
postfix start

The process has no result. it seems it never finished.

Could someone tell me how to repair Postfix, or where is the error log.
Thanks.

It seems my Postfix is out of control.
After run
$ postfix stop
postfix/postfix-script: stopping the Postfix mail system

I run this:
$ ps -aux | grep postfix

result:

Many many lines like above shows...
I'm using Zimbra 4.5.4 RHEL4_64.
It works well before the system crash.

Yep, stop all of those.
If you can't, then kill them with a sig 9

Run fsck to see if you have any disk errors, and run the zmfixperms script located in the libexec dir

If that doesn't fix it, run
./install.sh -s

from the original install dir.

Thanks your reply
Before I follow you, I want to know if "zmfixperms" or "./install.sh -s" may destory the users mail account and mailbox?
Because I have a lot of user using the mailserver.

[jholder]

Nope.

However, it's always a good idea to backup your data.
