Postfix errors and testing

Postfix error :

 #postfix start
 #postfix stop

 if it says postfix is not running

 check the application at port no 25 and stop that application (might be  sendmail) and try once again.

 #postfix start
 #postfix stop

If postfix stops .Then its working.



For errors check this log file check /var/log/maillog
