[Dovecot] Fatal: open() failed for /var/run/dovecot/login: Permission denied

[Andy Yen]

I keep getting this message when I try to start dovecot using the -F option.
Fatal: open() failed for /var/run/dovecot/login: Permission denied

Checking /var/run/dovecot/login folder permissions does not seem to 
indicate anything wrong as root has all the permissions it needs.  If I 
am not mistaken, dovecot can run as root while in the login directory 
correct?

When I try to start the dovecot service, it fails with the message:
dovecot dead but subsys locked.

Can anybody help me resolve this issue?

I am running RHEL5.4.

Thanks in advance.
