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.
Add a certificate scheme for using an existing ACME certificate without
setting up Nginx.
Also use names instead of magic numbers for certificate schemes.
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.

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.
Previously, the static Junk mailbox was used in sieve script to move
spam messages. This patch gets the Junk mailbox defined in the dovecot
mailboxes attribute instead.
Fixes#224
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.
Previously all the xapian files and logs would be stored in the same
folder for all users. This couid probably lead to weird situations where
all users get the same search results.
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.
Fixes#205
The line type of this option make its concatenation cleaner: the user
doesn't have to manually add `\n` to its policydSPFExtraConfig value
when debug in set.
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.
`services.postfix.extraConfig` is just a string while the
`services.postfix.config` option configures the same thing but with a
typed attrset instead which is easier to manipulate and override in Nix.
