This allows the definition of a custom derivation of Exim,
which can be used to enable custom features such as LDAP and PAM support.
The default behaviour remains unchanged (defaulting to pkgs.exim).
The pull request that added dhparams (#39507) was made at the time where
the dhparams module overhaul (#39526) wasn't done yet, so it's still
using the old mechanics of the module.
As stated in the release notes:
Module implementers should not set a specific bit size in order to let
users configure it by themselves if they want to have a different bit
size than the default (2048).
An example usage of this would be:
{ config, ... }:
{
security.dhparams.params.myservice = {};
environment.etc."myservice.conf".text = ''
dhparams = ${config.security.dhparams.params.myservice.path}
'';
}

The dovecot bump to 2.3.1 caused the dovecot service to fail to start
because it would try to chgrp sockets to dovecot whereas our default
dovecot group is called dovecot2.
`services.postfix.config` is now correctly merged with the default attrset
specified in the module. Some options that are lists in postfix also
have to be lists in nix to be merged correctly. Other default options are
now set with `mkDefault` so they can be overridden via the module system.
The current `remotes` option is a string option containing nullmailer remote
definitions. However, those definitions may contain secret credentials and
should therefore not be put world-readable in the nix store.
I added a `remotesFile` option, which allows to specify a path to the remotes
definition file instead. This way, the definitions can be kept outside of the
nix store with more secure file permissions.
Spamassassin expects its system-wide configuration at /etc/spamassassin, and
some user tools (like sa-learn) need to read those configuration files.
Therefore, we provide a symlink from /etc/spamassassin to the appropriate Nix
store path to make sure those tools work without the user having to pass an
elaborate --siteconfig path that, potentially, changes every time the system
updates.
Fixes https://github.com/NixOS/nixpkgs/issues/29414.
This option got introduced in 7904499542
and it didn't check whether mailUser and mailGroup are null, which they
are by default.
Now we're only creating the user if createMailUser is set in conjunction
with mailUser and the group if mailGroup is set as well.
I've added a NixOS VM test so that we can verify whether dovecot works
without any additional options set, so it serves as a regression test
for issue #29466 and other issues that might come up with future changes
to the Dovecot service.

I realize that advanced users like to configure services with Nix
attrsets, but I don't think we should remove the option to use the
(configuration) language provided by upstream.
