Updated Postfix not running after transferring over users from older postfix
 

I recently moved over user from an old box running postfix(v 2.0.16) over to rhel 6 running postfix (v mail_version = 2.6.6). ive tried to make sure all the files are of correct permissions and that the main.cf file is configured corectly.
However there is something wrong as when i run postfix:
service postfix server
i get no error but when checking the status:service postfix status i get:
master dead but pid file exists

Looking into /var/log/mailog i find this line being the issue:

Feb 25 16:24:39 puny1 postfix/master[3517]: fatal: fifo_listen: create fifo public/pickup: Permission denied


I gather this is a file permission issue and ive tried to make sure the public folder in /var/spool/postfix is correctly set but still no avail.
Any help or direction will be much appreciated.

Hello,

Check the permissions on main.cf and master.cf if they are correctly. Then try
If you get an error stopping or starting postfix, delete the pid file manually and try again.

Kind regards,

Eric

EricTRA, thanks for the response.
I have made sure the permissions are the same, which is root to have read write perissions for both files mentioned above.
when starting stopping there is no error appearing on screen. However the permission error is still appearing in the mail log as mentioned in my previous mail above.
The file that is being accessed is the public file within postfix. the permissions on the files in /var/postfix folder are exactly the same that im bringing over from the old postfix server.
