Hello kind people,

Any help on this would be appreciated.

Dovecot v1.2.16. Freshly installed today. Comes up with this during 
service startup (CentOS 5.5 -> "service dovecot start"
<ENTER> :

---------------------------
Restarting DovecotFatal: ssl_listen: Can't resolve address required: Name or
service not known
---------------------------

Here's "dovecot -n" :

ssl_listen should be a port or address:port to listen on with SSL enabled.
'required' is not a valid hostname on your network.
