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.
* The module uses `stringSplit` but it should be `splitString`
* `rmilter` doesn't actually support binding to multiple sockets.
Therefore, bind to the last one specified if `socketActivation` is
`false`.
I also believe there is a bug in this module related to systemd
`ListenStream`. If `socketActivation` is true, Postfix gets
connection timeouts trying to connect to one of the `ListenStream`
inet addresses. I don't know enough about `ListenStream` passing
connections on to `fd:3` to understand what's going on.
These changes are in production (with `socketActivation = false`) via NixOps.
From Postfix documentation:
With this setting, the Postfix SMTP server will not reject mail with "User
unknown in local recipient table". Don't do this on systems that receive mail
directly from the Internet. With today's worms and viruses, Postfix will become
a backscatter source: it accepts mail for non-existent recipients and then
tries to return that mail as "undeliverable" to the often forged sender
address.
Make sure that the output of the sieve compiler produces files that
have a newer time stamp than the source sieve script. Otherwise you
get errors in the logs about Dovecot not being able to compile do to a
permission issue.
The services/networking directory is already quite polluted and the
first point where I was looking for the offlineimap module was in
services/mail and didn't find it there.
Offlineimap already has IMAP in its name and clearly belongs to the
"mail" category so let's move it there.
Tested by evaluating a configuration with services.offlineimap enabled.

Systemd upstream provides targets for networking. This also includes a target network-online.target.
In this PR I remove / replace most occurrences since some of them were even wrong and could delay startup.
Instead of using this option, please modify the dovecot package by means of an
override. For example:
nixpkgs.config.packageOverrides = super: {
dovecot = super.dovecot.override { withPgSQL = true; };
};
Closes https://github.com/NixOS/nixpkgs/issues/14097.
Make top level /var/lib/postfix as root:root 0755
After generating custom configs in /var/lib/postfix/conf,
`postfix set-permissions` called, to perform all required tricks
related to queue handling (postfix use file mode bits to keep
some internal statuses, so `chmod -R` not recommended by authors,
see comments in $out/libexec/postfix/post-install for details)
Also post-install script was patched, to skip permission check/update
for files inside $out, as well as symlinks following to $NIX_STORE.
Config file `main.cf` extended with all default directory locations,
to prevent post-install script from guessing and overwrite them.
And finally all actions in activation script snippets performed
by postmap/postalias/postfix tools from current build, not random one
from paths.
- add missing types in module definitions
- add missing 'defaultText' in module definitions
- wrap example with 'literalExample' where necessary in module definitions
Regression introduced by 3891d3e654.
Merging multiple options with type "str" won't work and give an
evaluation error. For extra configuration lines in the Postfix config it
really should be "lines", especially because even the description
mentions "extra lines".

This reverts commit 88f4b75a00 and fixes the
recipientDelimiter config option. Till then the camel case variant was used
while recipient_delimiter would have been right.
This solves the problem of e.g. mutt not finding mail unless the user
sets MAIL=/var/spool/mail/$USER.
The default MAIL variable seems come from bash. Reasons for adding
symlink instead of changing MAIL default in bash:
- No need to rebuild world
- FHS recommends /var/mail over /var/spool/mail anyway[1]. Better fix
NixOS mail location than change MAIL in bash to something that doesn't
work on non-NixOS (however unlikely that users run nixpkgs bash on a
non-NixOS distro...).

Absolute path is required when one has such postfix configuration
where he/she needs to specify the actual (real) path to active dovecot
config.
Without this commit applied, the dovecot is running in such way:
/nix/store/hashAAA-dovecot-ver/sbin/dovecot -F -c /nix/store/hashBBB-dovecot2.conf
and postfix can't be aware of the value of "hashBBB" via services.postfix.extraConfig = '' ... '';
(it can only be aware of "hashAAA" with ${pkgs.dovecot} parameter)
Also enable Restart on-failure.
Edit: set RestartSec to 1s
postfix 2.11 is much more humane with respect to disk writes since it uses
sockets (which do not change inodes on accesses) instead of fifos (which do).
