Hi all,
I'm using Webmin 1.831, Virtualmin 5.07, with Authentic theme 18.49-7 on Centos 7.
My postfix server is currently (accidentally) running outside of the Webmin / systemctl framework.
The webmin gui shows it as not running, and systemctl reports it as failed:
~ $ systemctl status postfix.service
● postfix.service - Postfix Mail Transport Agent
Loaded: loaded (/usr/lib/systemd/system/postfix.service; enabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Mon 2017-02-13 13:06:29 GMT; 3 months 29 days ago
Main PID: 1670 (code=exited, status=1/FAILURE)
However, postfix is actually up and running (and working properly):
~ $ ps -ef |grep postfix

From here, what is the safest way to stop this existing postfix daemon (without loss of mail / danger of leaving stray lock files etc) so I can restart it properly using systemctl? I'd prefer not to reboot the server if I don't have to.
Cheers!
Try with
systemctl unmask ######. About what is the safest way to restart postfix, usereloadinstead ofrestart, Either way you should focus on repairing your postfix and then the rest.- I often come to the conclusion that my brain has too many tabs open. -

Thanks diabolico - weird thing was there was actually nothing wrong with the postfix config.
Postfix was running outside systemctl, but even "/sbin/postfix status" claimed that it wasn't running (so I couldn't use "/sbin/postfix stop|reload" to stop or reload it.) "/sbin/postfix check" didn't report config errors.
In the end I rebooted the server and once again it came up with postfix running but outside systemctl (i.e. webmin still reported it as stopped.) This time, however, "/sbin/postfix status" recognised the running instance, so I could stop it using "/sbin/postfix stop". Having done that, I could then restart it using systemctl and now things are back to normal - postfix came up normally via systemctl after a second reboot.
