[Dovecot] auth-master permission error

[greno at verizon.net]

Ok, this turned out to be SELinux.

If I turn off SELinux then I can start Dovecot using init.d.

So now I tried to send a test mail using telnet:

# telnet localhost smtp
Trying 127.0.0.1...
Connected to localhost.

So I checked and 'deliver' is not in /usr/lib/dovecot.  It is in /usr/libexec/dovecot.  So how do I fix this?  Here is what is in postfix master.cf:
dovecot   unix  -       n       n       -       -       pipe
    flags=DRhu user=vmail:vmail argv=/usr/libexec/dovecot/deliver -d ${recipient}

So why is it referencing /usr/lib/dovecot/deliver ????

Thanks,
Gerry
