[Nix-dev] NixOS Postfix service module config: why emptylocal_recipient_maps value?

[aldiyen]

Ah, fair enough then. I'd be happy to make it configurable, and perhaps
make it so that the default behavior is not to override Postfix's default
value if no value is set in the NixOS configuration. I've already forked
the repo and made appropriate changes locally in order to work around the
issue

What's the policy on changing modules created by other people? I didn't see
any information on it in any of the stuff on the web site. I know I'll have
to submit a pull request and all, but are there any conventions on what
sorts of changes are / aren't accepted?
