[ampun]

Hi,
after follow dovecot conversion step, http://www.directadmin.com/features.php?id=590
everything is ok, but..

pop3 is not working again.

restart dovecot

#service dovecot restart
Shutting down dovecot: [FAILED]
Starting dovecot: [ OK ]

then pop3 & imap down again, then i restart again
Shutting down dovecot: [FAILED]
Starting dovecot: [ OK ]


POP3 was working properly before installing dovecot. I have checked port 110, there's no service using it.

how to fix this problem? there're serveral emails & domains.
