Sorry for the lack of info in earlier post.
Think the main issue is I can't even start up postfix :
# postfix set-permissions
[root@etc]# postfix start
postfix/postfix-script: starting the Postfix mail system
[root@ etc]# postfix reload
postfix/postfix-script: fatal: the Postfix mail system is not running
I googed for "master.lock unable exclusive lock" but it's mostly on
MacOS & editing php.ini doesn't help:
Relevant error from /var/log/maillog
