This switches the full-text search plugin from fts-xapian to
fts-flatcurve, the now preferred indexer still powered by Xapian,
which will be integrated into Dovecot core 2.4.
This sets a sane minimal configuration for the plugin with
international language support.
The plugin options marked as "advanced" in Dovecot's documentation
aren't re-exposed for simplicity. They can nevertheless be overridden
by module consumers by directly setting keys with
`services.dovecot2.pluginSettings.fts_*`.
The `fullTextSearch.{memoryLimit,maintenance}` options are removed as
they are no longer needed for this plugin, which tops at 256MB of RAM
usage by default and incrementally optimises its index.
GitLab: closes https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/issues/239
fts xapian does not publish configuration changes in a changelog. As a
result, some options that nixos mailserver was setting for it have been
ignored for several years. New options (process_limit) are now
recommended. This adapts the module to these changes.
The default value of partial= is 2, but fts_xapian 1.8.3 now requires it
to be at least 3, and fails loudly in case it is 2. As a result, this
change is required to support fts_xapian 1.8.3 and later.
Sets up a declaratively configured OpenLDAP instance with users alice
and bob. They each own one email address,
First we test that postfix can communicate with LDAP and do the expected
lookups using the defined maps.
Then we use doveadm to make sure it can look up the two accounts.
Next we check the binding between account and mail address, by logging
in as alice and trying to send from bob@example.com, which alice is not
allowed to do. We expect postfix to reject the sender address here.
Finally we check mail delivery between alice and bob. Alice tries to
send a mail from alice@example.com to bob@example.com and bob then
checks whether it arrived in their mailbox.
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
Before using Niv, we were following channels meaning we can not
reproduce CI jobs easily.
In this change, we use Niv to pin these dependencies. We are also
addding a tests/default.nix to be able to run these tests locally.
For instance, to run the test extern.nix on the nixpkgs-19.09 release:
nix-build tests/default.nix -A extern.nixpkgs_19_09
Fixes#178
The current version fetches clamav-db-files from gitlab,
in the master branch. This is currently broken as the files
were removed, and does not allow to ensure a fixture update
does not break the test
