Prior to this fix, changes to certain settings would not be applied
automatically and users would have to know to manually restart the
affected service. A prime example of this is
`services.mailman.hyperkitty.baseUrl`, or various things that affect
`mailman3/settings.py`
Previously, some files were copied into the Nixpkgs tree, which meant
we wouldn't easily be able to update them, and was also just messy.
The reason it was done that way before was so that a few NixOS
options could be substituted in. Some problems with doing it this way
were that the _package_ changed depending on the values of the
settings, which is pretty strange, and also that it only allowed those
few settings to be set.
In the new model, mailman-web is a usable package without needing to
override, and I've implemented the NixOS options in a much more
flexible way. NixOS' mailman-web config file first reads the
mailman-web settings to use as defaults, but then it loads another
configuration file generated from the new services.mailman.webSettings
option, so _any_ mailman-web Django setting can be customised by the
user, rather than just the three that were supported before. I've
kept the old options, but there might not really be any good reason to
keep them.
We already had python3Packages.mailman, but that's only really usable
as a library. The only other option was to create a whole Python
environment, which was undesirable to install as a system-wide
package.
It's likely that a user might want to set multiple values for
relay_domains, transport_maps, and local_recipient_maps, and the order
is significant. This means that there's no good way to set these
across multiple NixOS modules, and they should probably all be set
together in the user's Postfix configuration.
So, rather than setting these in the Mailman module, just make the
Mailman module check that the values it needs to occur somewhere, and
advise the user on what to set if not.
This replaces all Mailman secrets with ones that are generated the
first time the service is run. This replaces the hyperkittyApiKey
option, which would lead to a secret in the world-readable store.
Even worse were the secrets hard-coded into mailman-web, which are not
just world-readable, but identical for all users!
services.mailman.hyperkittyApiKey has been removed, and so can no
longer be used to determine whether to enable Hyperkitty. In its
place, there is a new option, services.mailman.hyperkitty.enable. For
consistency, services.mailman.hyperkittyBaseUrl has been renamed to
services.mailman.hyperkitty.baseUrl.
Using a custom path in the Nix store meant that users of the module
couldn't add their own config files, which is a desirable feature. I
don't think avoiding /etc buys us anything.
Motivation:
if enableQuota is true, mail plugins cannot be enabled in extraConfig
because of the problem described here:
https://doc.dovecot.org/configuration_manual/config_file/config_file_syntax/#variable-expansion
doveconf: Warning: /etc/dovecot/dovecot.conf line 8: Global setting
mail_plugins won't change the setting inside an earlier filter at
/etc/dovecot/dovecot.conf line 5 (if this is intentional, avoid this
warning by moving the global setting before /etc/dovecot/dovecot.conf
line 5)
The php installer creates a random one, but we bypass it, so we have
to create one ourselves.
This should be backward compatible as encryption is used for session
cookies only: users at the time of the upgrade will be logged out but
nothing more.

If the database is local, use postgres peer authentication.
Otherwise, use a password file.
Leave database initialisation to postgresql.ensure*.
Leave /var/lib/roundcube creation to systemd.
Run php upgrade script as unpriviledged user.
Supporting a path here is important because it allows e.g. fetching a
configuration from a URL. To do this and provide the configuration as
a string, IFD would be necessary. It's just written into a path
anyway.
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file
When mailman-web restarts, it removes the generated "static" directory. This
breaks a currently running httpd process, which needs a re-start, too, to
obtain a new handle for the newly generated path.
Any system uid will do, so we let the system allocate
one for us. The 'mailman' group is gone entirely since
we don't need it. Users who wish to run the 'mailman'
administration utility can do so via 'sudo':
$ sudo -u mailman mailman info
Also, simplify the syntax of our user.users entry to
rely on an attribute set rather than a list.
The `keys.target` is used to indicate whether all NixOps keys were
successfully uploaded on an unattended reboot. However this can cause
startup issues e.g. with NixOS containers (see #67265) and can block
boots even though this might not be needed (e.g. with a dovecot2
instance running that doesn't need any of the NixOps keys).
As described in the NixOps manual[1], dependencies to keys should be
defined like this now:
``` nix
{
systemd.services.myservice = {
after = [ "secret-key.service" ];
wants = [ "secret-key.service" ];
};
}
```
However I'd leave the issue open until it's discussed whether or not to
keep `keys.target` in `nixpkgs`.

The new option services.postfix.localRecipients allows
configuring the postfix option 'local_recipient_maps'. When
set to a list of user names (or patterns), that map
effectively replaces the lookup in the system's user
database that's used by default to determine which local
users are valid.
This option is useful to explicitly set local users that are
allowed to receive e-mail from the outside world. For local
injection i.e. via the 'sendmail' command this option has no
effect.
When using a different database, the evaluation fails as
`config.services.postgresql.package` is only set if `services.postgresql` is enabled.
Also, the systemd service shouldn't have a relation to postgres if a
remote database is used.
With this option it's possible to specify a custom expression for
`roundcube`, i.e. a roundcube environment with third-party plugins as
shown in the testcase.
When reworking the rspamd workers I disallowed `proxy` as a type and
instead used `rspamd_proxy` which is the correct name for that worker
type. That change breaks peoples existing config and so I have made this
commit which allows `proxy` as a worker type again but makes it behave
as `rspamd_proxy` and prints a warning if you use it.
The `rmilter` module has options for configuring `postfix` to use it but
since that module is deprecated because rspamd now has a builtin worker
that supports the milter protocol this commit adds similar `postfix`
integration options directly to the `rspamd` module.
The lines stored in `extraConfig` and `worker.<name?>.extraConfig`
should take precedent over values from included files but in order to do
this in rspamd UCL they need to be stored in a file that then gets
included with a high priority. This commit uses the overrides option to
store the value of the two `extraConfig` options in `extra-config.inc`
and `worker-<name?>.inc` respectively.
When the workers option for rspamd was originally implemented it was
based on a flawed understanding of how workers are configured in rspamd.
This meant that while rspamd supports configuring multiple workers of
the same type, so that different controller workers could have different
passwords, the NixOS module did not support this because it would write
an invalid configuration file if you tried.
Specifically a configuration like the one below:
```
workers.controller = {};
workers.controller2 = {
type = "controller";
};
```
Would result in a rspamd configuration of:
```
worker {
type = "controller";
count = 1;
.include "$CONFDIR/worker-controller.inc"
}
worker "controller2" {
type = "controller";
count = 1;
}
```
While to get multiple controller workers it should instead be:
```
worker "controller" {
type = "controller";
count = 1;
.include "$CONFDIR/worker-controller.inc"
}
worker "controller" {
type = "controller";
count = 1;
}
```
