nixos/mailman: make Postfix support optional (provided you configure the MTA yourself)

Browse Source 
Mailman can now work with MTAs other than Postfix. You'll have to configure
it yourself using the options in `services.mailman.settings.mta`.

This addition is reflected in the release notes for 21.03.

Mailman also supports other MTA, though with a little bit more configuration. For example, to use Mailman with Exim, you can use the following settings:
<programlisting>{ config, ... }: {
services = {
mailman = {
enable = true;
siteOwner = "mailman@example.org";
<link linkend="opt-services.mailman.enablePostfix">enablePostfix</link> = false;
settings.mta = {
incoming = "mailman.mta.exim4.LMTP";
outgoing = "mailman.mta.deliver.deliver";
lmtp_host = "localhost";
lmtp_port = "8024";
smtp_host = "localhost";
smtp_port = "25";
configuration = "python:mailman.config.exim4";
};
};
exim = {
enable = true;
# You can configure Exim in a separate file to reduce configuration.nix clutter
config = builtins.readFile ./exim.conf;
};
};
}</programlisting>

<para>
The exim config needs some special additions to work with Mailman. Currently
NixOS can't manage Exim config with such granularity. Please refer to
<link xlink:href="https://mailman.readthedocs.io/en/latest/src/mailman/docs/mta.html">Mailman documentation</link>
for more info on configuring Mailman for working with Exim.
