Postfix MTA service not working! CentOS 6

I was having problems with keeping the Postfix MTA configured and running with Puppet. Each time Puppet ran it detected that it wasn't running and attempted to start it with no avail. The error when looking at the service was this:

# service postfix status
master dead but pid file exists

But removing the pid file didn't not help:

# locate postfix|grep pid
/var/spool/postfix/pid
/var/spool/postfix/pid/master.pid
[root@webtest ~]# rm /var/spool/postfix/pid/master.pid
rm: remove regular file `/var/spool/postfix/pid/master.pid'? y
[root@webtest ~]# service postfix status
master dead but subsys locked

So looking at the logs this was seen:

# tail  /var/log/maillog
Oct 30 19:44:06 webtest postfix/master[8005]: fatal: bind 127.0.0.1 port 25: Address already in use
Oct 30 20:09:49 webtest postfix/postfix-script[10053]: starting the Postfix mail system
Oct 30 20:09:49 webtest postfix/master[10054]: fatal: bind 127.0.0.1 port 25: Address already in use
Oct 30 20:10:04 webtest postfix/postfix-script[10602]: starting the Postfix mail system
Oct 30 20:10:04 webtest postfix/master[10603]: fatal: bind 127.0.0.1 port 25: Address already in use
Oct 30 20:10:53 webtest postfix/postfix-script[11037]: starting the Postfix mail system

The problem looks like another MTA was running hogging port 25. A quick ps for sendmail revealed nothing, but there's another agent that comes with CentOS 6:

[root@webtest ~]# ps -ef|grep send
root     12448  9780  0 20:16 pts/0    00:00:00 grep send
[root@webtest ~]# ps -ef|grep exim
root     12109  9780  0 20:22 pts/0    00:00:00 grep exim
exim     57456     1  0 Jul07 ?        00:00:00 /usr/sbin/exim -bd -q1h

[root@webtest ~]# service exim stop
Shutting down exim:                                        [  OK  ]
[root@webtest ~]# chkconfig exim off

Now a Puppet run should install and run Postfix without a problem:

# puppet agent -t
