Ok...
[root@mail2 pid]# service postfix stop
[root@mail2 pid]# service postfix start
Starting postfix: [ OK ]
[root@mail2 pid]# service postfix status
master dead but pid file exists
That suggests that postfix (actually master) is dying abnormally for
some unknown reason.
You might do "postfix check" to see if it finds any configuration errors.
Then you might do "postfix start -Dv" to run in debugging mode with
verbose logging, and see if you can find what's killing master.

Subject: Re: can't get server to start postfix
after a reboot, you could just try "postfix stop" and delete the lock
file, then "postfix start"
to find zombie processes, you could try "pstree" (shows a tree of
processes & sub-processes, in the order they were started at init time -
note that none of them are named postfix - the top-level process is
named "master") - you might have to install the tools, I think they're
part of the "process tools" package on Debian (but that's completely
from memory) - google is yourf friend

you have a zombie master process hanging around. Stop postfix. Get a list of
all running processes and check if there's a orphaned master process hanging
around. Kill it. Start postfix.
