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.
`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.
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.

docecot -> dovecot
Also, `indexDir` is not expecting to see %d/%n being passed to that
parameter, so remove that to make it easier to cpy the path into
there.
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.
