## Release notes
|
||||
|
||||
### nixos-20.03
|
||||
|
||||
- Rspamd is upgraded to 2.0 which deprecates the SQLite Bayes
|
||||
backend. We then moved to the Redis backend (the default since
|
||||
Rspamd 2.0). If you don't want to relearn the Redis backend from the
|
||||
scratch, we could manually run
|
||||
|
||||
rspamadm statconvert --spam-db /var/lib/rspamd/bayes.spam.sqlite --ham-db /var/lib/rspamd/bayes.ham.sqlite -h 127.0.0.1:6379 --symbol-ham BAYES_HAM --symbol-spam BAYES_SPAM
|
||||
|
||||
See the [Rspamd migration
|
||||
notes](https://rspamd.com/doc/migration.html#migration-to-rspamd-20)
|
||||
and [this SNM Merge
|
||||
Request](https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/merge_requests/164)

The scheme to use for managing TLS certificates:
|

Certificate Files. There are three options for these.
|
||||
|
||||
1. `manual`: you specify locations via {option}`mailserver.certificateFile` and
|
||||
{option}`mailserver.keyFile` and manually copy certificates there.
|
||||
2. `selfsigned`: you let the server create new (self-signed) certificates on the fly.
|
||||
3. `acme-nginx`: you let the server request certificates from [Let's Encrypt](https://letsencrypt.org)
|
||||
via NixOS' ACME module. By default, this will set up a stripped-down Nginx server for
|
||||
{option}`mailserver.fqdn` and open port 80. For this to work, the FQDN must be properly
|
||||
configured to point to your server (see the [setup guide](setup-guide.rst) for more information).
|
||||
4. `acme`: you already have an ACME certificate set up (for example, you're already running a TLS-enabled
|
||||
Nginx server on the FQDN). This is better than `manual` because the appropriate services will be reloaded
|
||||
when the certificate is renewed.
|
||||
1) You specify locations and manually copy certificates there.
|
||||
2) You let the server create new (self signed) certificates on the fly.
|
||||
3) You let the server create a certificate via `Let's Encrypt`. Note that
|
||||
this implies that a stripped down webserver has to be started. This also
|
||||
implies that the FQDN must be set as an `A` record to point to the IP of
|
||||
the server. In particular port 80 on the server will be opened. For details
|
||||
on how to set up the domain records, see the guide in the readme.

A Complete Backup Guide
|
||||
=======================
|
||||
|
||||
First off you should have a backup of your ``configuration.nix`` file
|
||||
where you have the server config (but that is already in a git
|
||||
repository right?)
|
||||
This is really easy. First off you should have a backup of your
|
||||
``configuration.nix`` file where you have the server config (but that is
|
||||
already in a git repository right?)
|
||||
|
||||
Next you need to backup ``/var/vmail`` or whatever you have specified
|
||||
for the option ``mailDirectory``. This is where all the mails reside.

``catchAll`` users can't send email as user other than themself
|
||||
---------------------------------------------------------------
|
||||
|
||||
To allow a ``catchAll`` user to send mail with the address used as
|
||||
recipient, the option ``aliases`` has to be used instead of ``catchAll``.
|
||||
|
||||
For instance, to allow ``user@example.com`` to catch all mails to the
|
||||
domain ``example.com`` and send mails with any address of this domain:
|
||||
|
||||
|
||||
.. code:: nix
|
||||
|
||||
mailserver.loginAccounts = {
|
||||
"user@example.com" = {
|
||||
aliases = [ "@example.com" ];
|
||||
};
|
||||

is very slow and IO intensive. To speed body searches up, it is possible to
|
||||
*index* emails with a plugin to dovecot, ``fts_xapian``.
|
||||
|
||||
Enabling full text search
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To enable indexing for full text search here is an example configuration.
|
||||
|
||||
.. code:: nix
|
||||
|
||||
{
|
||||
mailserver = {
|
||||
# ...
|
||||
fullTextSearch = {
|
||||
enable = true;
|
||||
# index new email as they arrive
|
||||
autoIndex = true;
|
||||
# this only applies to plain text attachments, binary attachments are never indexed
|
||||
indexAttachments = true;
|
||||
enforced = "body";
|
||||
};
|
||||
};
|
||||
}
|
||||
|
||||
|
||||
The ``enforced`` parameter tells dovecot to fail any body search query that cannot
|
||||
use an index. This prevents dovecot to fall back to the IO-intensive brute
|
||||
force search.
|
||||
|
||||
If you set ``autoIndex`` to ``false``, indices will be created when the IMAP client
|
||||
issues a search query, so latency will be high.
|
||||
|
||||
Resource requirements
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Indices created by the full text search feature can take more disk
|
||||
space than the emails themselves. By default, they are kept in the
|
||||
emails location. When enabling the full text search feature, it is
|
||||
recommended to move indices in a different location, such as
|
||||
(``/var/lib/dovecot/indices``) by using the option
|
||||
``mailserver.indexDir``.
|
||||
|
||||
.. warning::
|
||||
|
||||
When the value of the ``indexDir`` option is changed, all dovecot
|
||||
indices needs to be recreated: clients would need to resynchronize.
|
||||
|
||||
Indexation itself is rather resouces intensive, in CPU, and for emails with
|
||||
large headers, in memory as well. Initial indexation of existing emails can take
|
||||
hours. If the indexer worker is killed or segfaults during indexation, it can
|
||||
be that it tried to allocate more memory than allowed. You can increase the memory
|
||||
limit by eg ``mailserver.fullTextSearch.memoryLimit = 2000`` (in MiB).
|
||||
|
||||
Mitigating resources requirements
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
You can:
|
||||
|
||||
* disable indexation of attachements ``mailserver.fullTextSearch.indexAttachments = false``
|
||||
* reduce the size of ngrams to be indexed ``mailserver.fullTextSearch.minSize`` and ``maxSize``
|
||||
* disable automatic indexation for some folders with
|
||||
``mailserver.fullTextSearch.autoIndexExclude``. Folders can be specified by
|
||||
name (``"Trash"``), by special use (``"\\Junk"``) or with a wildcard.

How to Develop SNM
|

==================

Run NixOS tests

---------------
|

|

To run the test suite, you need to enable `Nix Flakes

||||
|

::
|
||||
|

$ nix flake check -L
|
||||
|
||||
Since Nix doesn't garantee your machine have enough resources to run
|
||||
all test VMs in parallel, some tests can fail. You would then haev to
|
||||
run tests manually. For instance:
|
||||
|
||||
::
|
||||
|
||||
$ nix build .#hydraJobs.x86_64-linux.external-unstable -L
|
||||
|
||||
$ nix-build tests -A extern.nixpkgs_20_03
|
||||
$ nix-build tests -A intern.nixpkgs_unstable

|
||||
All related LDAP options are described in the `LDAP options section
|

<options.html#mailserver-ldap>`_ and the `LDAP test
|
||||
<https://gitlab.com/simple-nixos-mailserver/nixos-mailserver/-/blob/master/tests/ldap.nix>`_
|
||||
provides a getting started example.
|
||||
|
||||
.. note::
|
||||
The LDAP support can not be enabled if some accounts are also defined with ``mailserver.loginAccounts``.

Setup Guide
|

===========
|
||||
A Complete Setup Guide
|
||||
======================
|
||||
|
||||
Mail servers can be a tricky thing to set up. This guide is supposed to
|
||||
run you through the most important steps to achieve a 10/10 score on
|
||||
`<https://mail-tester.com>`_.
|
||||
``mail-tester.com``.
|
||||
|
||||
What you need is:
|
||||
What you need:
|
||||
|
||||
- a server running NixOS with a public IP
|
||||
- a domain name.
|
||||
- A server with a public IP (referred to as ``server-IP``)
|
||||
- A Fully Qualified Domain Name (``FQDN``) where your server is
|
||||
reachable, so that other servers can find yours. Common FQDN include
|
||||
``mx.example.com`` (where ``example.com`` is a domain you own) or
|
||||
``mail.example.com``. The domain is referred to as ``server-domain``
|
||||
(``example.com`` in the above example) and the ``FQDN`` is referred
|
||||
to by ``server-FQDN`` (``mx.example.com`` above).
|
||||
- A list of domains you want to your email server to serve. (Note that
|
||||
this does not have to include ``server-domain``, but may of course).
|
||||
These will be referred to as ``domains``. As an example,
|
||||
``domains = [ example1.com, example2.com ]``.
|
||||
|
||||
.. note::
|
||||
|
||||
In the following, we consider a server with the public IP ``1.2.3.4``
|
||||
and the domain ``example.com``.
|
||||
|
||||
First, we will set the minimum DNS configuration to be able to deploy
|
||||
an up and running mail server. Once the server is deployed, we could
|
||||
then set all DNS entries required to send and receive mails on this
|
||||
server.
|
||||
|
||||
Setup DNS A record for server
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Add a DNS record to the domain ``example.com`` with the following
|
||||
entries
|
||||
|
||||
==================== ===== ==== =============
|
||||
Name (Subdomain) TTL Type Value
|
||||
==================== ===== ==== =============
|
||||
``mail.example.com`` 10800 A ``1.2.3.4``
|
||||
==================== ===== ==== =============
|
||||
|
||||
You can check this with
|
||||
|
||||
::
|
||||
|
||||
$ ping mail.example.com
|
||||
64 bytes from mail.example.com (1.2.3.4): icmp_seq=1 ttl=46 time=21.3 ms
|
||||
...
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated. This
|
||||
DNS entry is required for the Let's Encrypt certificate generation
|
||||
(which is used in the below configuration example).
|
||||
|
||||
Setup the server
|
||||
~~~~~~~~~~~~~~~~
|
||||
A) Setup server
|
||||

|
||||
|
||||
The following describes a server setup that is fairly complete. Even
|
||||
though there are more possible options (see the `NixOS Mailserver
|
||||
options documentation <options.html>`_), these should be the most
|
||||
common ones.
|

After a ``nixos-rebuild switch`` your server should be running all

mail components.
|

After a ``nixos-rebuild switch --upgrade`` your server should be good to
|

go. If you want to use ``nixops`` to deploy the server, look in the
|
||||
subfolder ``nixops`` for some inspiration.
|
||||
|
||||
Setup all other DNS requirements
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
B) Setup everything else
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Set rDNS (reverse DNS) entry for server
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
Step 1: Set DNS entry for server
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Add a DNS record to the domain ``server-domain`` with the following
|
||||
entries
|
||||
|
||||
================ ===== ==== ======== =============
|
||||
Name (Subdomain) TTL Type Priority Value
|
||||
================ ===== ==== ======== =============
|
||||
``server-FQDN`` 10800 A ``server-IP``
|
||||
================ ===== ==== ======== =============
|
||||
|
||||
This resolves DNS queries for ``server-FQDN`` to ``server-IP``. You can
|
||||
test if your setting is correct by
|
||||
|
||||
::
|
||||
|
||||
ping <server-FQDN>
|
||||
64 bytes from <server-FQDN> (<server-IP>): icmp_seq=1 ttl=46 time=21.3 ms
|
||||
...
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
|
||||
|
||||
Step 2: Set rDNS (reverse DNS) entry for server
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Wherever you have rented your server, you should be able to set reverse
|
||||
DNS entries for the IP’s you own. Add an entry resolving ``1.2.3.4``
|
||||
to ``mail.example.com``.
|
||||
DNS entries for the IP’s you own. Add an entry resolving ``server-IP``
|
||||
to ``server-FQDN``
|
||||
|
||||
.. warning::
|
||||
|
||||
We don't recommend setting up a mail server if you are not able to
|
||||
set a reverse DNS on your public IP because sent emails would be
|
||||
mostly marked as spam. Note that many residential ISP providers
|
||||
don't allow you to set a reverse DNS entry.
|
||||
|
||||
You can check this with
|
||||
You can test if your setting is correct by
|
||||
|
||||
::
|
||||
|
||||
$ nix-shell -p bind --command "host 1.2.3.4"
|
||||
4.3.2.1.in-addr.arpa domain name pointer mail.example.com.
|
||||
host <server-IP>
|
||||
<server-IP>.in-addr.arpa domain name pointer <server-FQDN>.
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
|
||||
|
||||
Set a ``MX`` record
|
||||
^^^^^^^^^^^^^^^^^^^
|
||||
Step 3: Set ``MX`` Records
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
|
||||
Add a ``MX`` record to the domain ``example.com``.
|
||||
|
||||
================ ==== ======== =================
|
||||
Name (Subdomain) Type Priority Value
|
||||
================ ==== ======== =================
|
||||
example.com MX 10 mail.example.com
|
||||
================ ==== ======== =================
|
||||
|
||||
You can check this with
|
||||
For every ``domain`` in ``domains`` do: \* Add a ``MX`` record to the
|
||||
domain ``domain``
|
||||
|
||||
::
|
||||
|
||||
$ nix-shell -p bind --command "host -t mx example.com"
|
||||
example.com mail is handled by 10 mail.example.com.
|
||||
| Name (Subdomain) | TTL | Type | Priority | Value |
|
||||
| ---------------- | ----- | ---- | -------- | ----------------- |
|
||||
| `domain` | | MX | 10 | `server-FQDN` |
|
||||
|
||||
You can test this via
|
||||
|
||||
::
|
||||
|
||||
dig -t MX <domain>
|
||||
|
||||
...
|
||||
;; ANSWER SECTION:
|
||||
<domain> 10800 IN MX 10 <server-FQDN>
|
||||
...
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
|
||||
|
||||
Set a ``SPF`` record
|
||||
^^^^^^^^^^^^^^^^^^^^
|
||||
Step 4: Set ``SPF`` Records
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Add a `SPF <https://en.wikipedia.org/wiki/Sender_Policy_Framework>`_
|
||||
record to the domain ``example.com``.
|
||||
|
||||
================ ===== ==== ================================
|
||||
Name (Subdomain) TTL Type Value
|
||||
================ ===== ==== ================================
|
||||
example.com 10800 TXT `v=spf1 a:mail.example.com -all`
|
||||
================ ===== ==== ================================
|
||||
|
||||
You can check this with
|
||||
For every ``domain`` in ``domains`` do: \* Add a ``SPF`` record to the
|
||||
domain ``domain``
|
||||
|
||||
::
|
||||
|
||||
$ nix-shell -p bind --command "host -t TXT example.com"
|
||||
example.com descriptive text "v=spf1 a:mail.example.com -all"
|
||||
| Name (Subdomain) | TTL | Type | Priority | Value |
|
||||
| ---------------- | ----- | ---- | -------- | ----------------- |
|
||||
| `domain` | 10800 | TXT | | `v=spf1 ip4:<server-IP> -all` |
|
||||
|
||||
You can check this with ``dig -t TXT <domain>`` similar to the last
|
||||
section. Note that ``SPF`` records are set as ``TXT`` records since
|
||||
RFC1035.
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated. If you
|
||||
want to use multiple servers for your email handling, don’t forget to
|
||||
add all server IP’s to this list.
|
||||
|
||||
Step 5: Set ``DKIM`` signature
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
In this section we assume that your ``dkimSelector`` is set to ``mail``.
|
||||
If you have a different selector, replace all ``mail``\ ’s below
|
||||
accordingly.
|
||||
|
||||
For every ``domain`` in ``domains`` do: \* Go to your server and
|
||||
navigate to the dkim key directory (by default ``/var/dkim``). There you
|
||||
will find a public key for any domain in the ``domain.txt`` file. It
|
||||
will look like
|
||||
``mail._domainkey IN TXT "v=DKIM1; r=postmaster; g=*; k=rsa; p=<really-long-key>" ; ----- DKIM mail for domain.tld``
|
||||
\* Add a ``DKIM`` record to the domain ``domain``
|
||||
|
||||
::
|
||||
|
||||
| Name (Subdomain) | TTL | Type | Priority | Value |
|
||||
| ---------------- | ----- | ---- | -------- | ----------------- |
|
||||
| mail._domainkey.`domain` | 10800 | TXT | | `v=DKIM1; p=<really-long-key>` |
|
||||
|
||||
You can check this with ``dig -t TXT mail._domainkey.<domain>`` similar
|
||||
to the last section.
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
|
||||
|
||||
Set ``DKIM`` signature
|
||||
^^^^^^^^^^^^^^^^^^^^^^
|
||||
Step 6: Set ``DMARC`` record
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
On your server, the ``opendkim`` systemd service generated a file
|
||||
containing your DKIM public key in the file
|
||||
``/var/dkim/example.com.mail.txt``. The content of this file looks
|
||||
like
|
||||
For every ``domain`` in ``domains`` do:
|
||||
|
||||
::
|
||||
- Add a ``DMARC`` record to the domain ``domain``
|
||||
|
||||
mail._domainkey IN TXT "v=DKIM1; k=rsa; s=email; p=<really-long-key>" ; ----- DKIM mail for domain.tld
|
||||
==================== ===== ==== ======== ====================
|
||||
Name (Subdomain) TTL Type Priority Value
|
||||
==================== ===== ==== ======== ====================
|
||||
\_dmarc.\ ``domain`` 10800 TXT ``v=DMARC1; p=none``
|
||||
==================== ===== ==== ======== ====================
|
||||
|
||||
where ``really-long-key`` is your public key.
|
||||
|
||||
Based on the content of this file, we can add a ``DKIM`` record to the
|
||||
domain ``example.com``.
|
||||
|
||||
=========================== ===== ==== ==============================
|
||||
Name (Subdomain) TTL Type Value
|
||||
=========================== ===== ==== ==============================
|
||||
mail._domainkey.example.com 10800 TXT ``v=DKIM1; p=<really-long-key>``
|
||||
=========================== ===== ==== ==============================
|
||||
|
||||
You can check this with
|
||||
|
||||
::
|
||||
|
||||
$ nix-shell -p bind --command "host -t txt mail._domainkey.example.com"
|
||||
mail._domainkey.example.com descriptive text "v=DKIM1;p=<really-long-key>"
|
||||
You can check this with ``dig -t TXT _dmarc.<domain>`` similar to the
|
||||
last section.
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
|
||||
|
||||
Set a ``DMARC`` record
|
||||
^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Add a ``DMARC`` record to the domain ``example.com``.
|
||||
|
||||
======================== ===== ==== ====================
|
||||
Name (Subdomain) TTL Type Value
|
||||
======================== ===== ==== ====================
|
||||
_dmarc.example.com 10800 TXT ``v=DMARC1; p=none``
|
||||
======================== ===== ==== ====================
|
||||
|
||||
You can check this with
|
||||
|
||||
::
|
||||
|
||||
$ nix-shell -p bind --command "host -t TXT _dmarc.example.com"
|
||||
_dmarc.example.com descriptive text "v=DMARC1; p=none"
|
||||
|
||||
Note that it can take a while until a DNS entry is propagated.
