a3b03d1b5a Use umask for race-free permission setting
Without using umask there's a small time window where paths are world
readable. That is a bad idea to do for secret files (e.g. the dovecot
code path).

33554e57ce Make the ldap test working
- The smtp/imap user name is now user@domain.tld
- Make the test_lookup function much more robust: it was now getting
  the correct file from the store.

08f077c5ca Add support for LDAP users
Allow configuring lookups for users and their mail addresses from an
LDAP directory. The LDAP username will be used as an accountname as
opposed to the email address used as the `loginName` for declarative
accounts. Mailbox for LDAP users will be stored below
`/var/vmail/ldap/<account>`.

Configuring domains is out of scope, since domains require further
configuration within the NixOS mailserver construct to set up all
related services accordingly.

Aliases can already be configured using `mailserver.forwards` but could
be supported using LDAP at a later point.

0c1801b489 dovecot: add dovecot_pigeonhole to system packages
`sieve-test` can be used to test sieve scripts.

It's annoying to nix-shell it in, because it reads the dovecot global
config and might stumble over incompatible .so files (as has happened
to me).

Simply providing it in $PATH is easier.

Add a certificate scheme for using an existing ACME certificate without
setting up Nginx.

Also use names instead of magic numbers for certificate schemes.

bd99079363 mail-server/dovecot: also learn spam/ham on APPEND
The current configuration doesn't work when moving spam from the INBOX
to Junk on a local maildir and then syncing the result to the IMAP
server with `mbsync(1)`. This is because `mbsync(1)` doesn't support a
mvoe-detection[1] (i.e. an IMAP MOVE which subsequently causes a Sieve
COPY according to RFC6851 which then triggers report{h,sp}am.sieve), but
instead sends `APPEND` (and removes the message in the src mailbox after
that).

Tested on my own mailserver that this fixes spam learning.

This doesn't work the other way round though because `APPEND` doesn't
have an origin. However, learning mails as spam happens more often than
learning spam as ham, so this is IMHO still useful.

rspamd: set default port for redis
Since we are now using services.redis.servers.rspamd, the port defaults
to 0 (i.e. do not bind a TCP socket). We still want rspamd to connect to
redis via TCP, so set a default port that is one above the default redis port.

a13526a6e3 nginx.nix: don't reload nginx
Fixes #227

Reloading nginx manually is actually not needed (see
nginx-config-reload.service) and causes deadlocks.

72748d7b6d Use the Junk mailbox name defined in the mailboxes attrs

mailboxes attribute instead.

93330c5453 Move indexDir option to the mailserver scope
This option has been initially in the mailserver.fullTextSearch
scope. However, this option modifies the location of all index files
of dovecot and not only those used by the full text search feature. It
is then more relevant to have this option in the mailserver top level
scope.

Moreover, the default option has been changed to null in order to keep
existing index files where they are: changing the index location means
recreating all index files. The fts documentation however recommend to
change this default location when enabling the fts feature.

Store FTS index in directory per domain & user to avoid collisions
Previously all the xapian files and logs would be stored in the same

all users get the same search results.

5f431207b3 postfix: forwarding emails of login accounts with keeping local copy
When a local account address is forwarded, the mails were not locally
kept. This was due to the way lookup tables were internally managed.

Instead of using lists to represent Postfix lookup tables, we now use
attribute sets: they can then be easily merged.

A regression test for
https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/issues/
has been added: it sets a forward on a local address and ensure an
email sent to this address is locally kept.

Fix passwfile update
Currently oneshot services are not re-run on NixOS activate and that
meant that you needed to manually restart `gen-passwd-file` for new
users to be available.

This commit removes the `gen-passwd-file` service and instead simply
calls the same script in the dovecot2 preStart.
