Otherwise, it wouldn't get restarted when a new system configuration
was activatad, so the Postfix configuration wouldn't be updated.
Fixes: fb2fa1b50f ("nixos/postfix: pull setup into its own unit")
* Removed unused `.package`-option.
* Added explicit postgresql support.
* Create a new meta-package for mailman to make sure each component has
the **same** python and packages can be downgraded if needed (e.g.
psycopg2 or sqlalchemy) without interfering with `pythonPackages` in any way.
* Document why certain python overrides are needed.
Closes#170035Closes#158424
Add support for enabling confinement
but does not enable it by default yet
because so far no module within NixOS uses confinement
hence that would set a precedent.
On first run, Postfix will refuse to start if it's started before
Mailman is up, because it'll try to read the map files generated
Mailman the first time it's started, and they won't exist yet. To fix
this, make sure Postfix isn't started until after Mailman is up if
they're both activated at the same time.
Consider a service that generates postfix lookup tables with
postmap(1), like Mailman. It needs the Postfix configuration file to
exist, but Postfix qmgr needs all the lookup tables its configured
with to exist before it starts. So the service that runs postmap
needs to run after the Postfix configuration and directory structure
is generated, but before Postfix itself is started. To enable this,
we split Postfix into two units: a oneshot unit that sets up the
configuration, and a longrun unit that supervises the Postfix
daemons. The postmap services can then be inserted in between these
two units.
* nixos/opensmtpd: Add missing brackets in config
Without this commit, you end up missing the sendmail suid wrapper,
because the "program" attribute would not override the right thing.
* Update nixos/modules/services/mail/opensmtpd.nix

Nullmailer expects that this directory exists (see
073f4e9c5d/doc/nullmailer-send.8 (L185)).
When it doesn't and an email cannot be sent due to a permanent failure
or has been in the queue longer than queuelifetime (7 days), message
"Can't rename file: No such file or directory" starts appearing in the
log and nullmailer never sends "Could not send message" notification.
This means that the user may never learn that his email was not
delivered.
