Jan 30 22:20:53 30006545 citadel: Citadel had trouble on starting up. We couldn't bind all ports you configured to be provided by citadel server. This means, citadel won't be the service provider for a specific service you configured it to.  If you don't want citadel to provide these services, turn them off in WebCit via Admin->System Preferences->Network.  The failed ports and sockets are: TCP port 0.0.0.0;25; (SMTP-MTA) s TCP port 0.0.0.0:587: (SMTP-MSA)     If you want citadel to provide you with that functionality, check the output of "netstat -lnp" on linux Servers or "netstat -na" on *BSD and stop the programm, that binds these ports.  You should eventually remove  their initscripts in /etc/init.d so that you won't get this trouble once more.  After that goto Administration -> Shutdown Citadel to make Citadel retry to bind this port.   To make both ways actualy take place restart the citserver with "sendcommand down"  The errors returned by the system were: citserver: Can't bind: Address already in usec ;
