In the Centos 6 /etc/postfix/mail.cf there are the lines:
debugger_command =
PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin
ddd $daemon_directory/$process_name $process_id & sleep 5
This parameter (?) does not show in the postconf -n listing. Also this
command takes these 3 lines in main.cf and I wonder how does postfix
know that these lines go together? Showing my lack of knowledge here...
One thing I am thinking MAY be the problem is that this line in main.cf
fails because of a warning comment in main.cf something to the concern
that if you are using an X-based debugger, you should be sure to set up
your XAUTHORITY environment variable before starting Postfix. And since
this is provided in the base install of Centos 6, I *hope* they got this
right...
