Package: postfix
Version: 3.2.2-1
Severity: normal
Tags: patch
Dear Maintainer,
* What led up to the situation?
trying to use multiple instances as stated in README.Debian.
* What exactly did you do (or not do) that was effective (or
ineffective)?
systemctl enable postfix@myinstance.service
systemctl start postfix
* What was the outcome of this action?
only the 'main' Postfix instance was started
* What outcome did you expect instead?
the instance 'myinstance' should also have been started
(at least that's how I understand README.Debian)
The following fix worked for me:

Now 'systemctl start postfix' starts and stops all enabled instances
of postfix.
However digging deeper into the possibilities of systemd there seems to
be an even better way to handle multiple instances!
Provided with postfix is a systemd-generator file in
/lib/systemd/system-generators/postfix-instance-generator
which takes care of the multi instance handling.
At first it did not work for me but applying this small change:

-------------------------------------------------------------------------
makes it behave as expected for me. It then creates symlinks in
/run/systemd/generator/postfix.service.wants/...
which makes the 'systemd enable postfix@myinstance.service'
command completely unnecessary.
Would be nice to have that alternative documented in README.Debian,
maybe even replacing the 'enable' variant because for me it looks
more elegant.
Thanks for considering applying my patches and your time
in maintaining the postifx package!
