Filtering mails
###############

We filter incoming mails with `Rspamd <https://rspamd.com>`_ which uses `multiple <https://rspamd.com/comparison.html>`_ filtering and statistical methods to generate a spam score, including (but not limited to) SPF, DMARC and DNS blacklists. Mails with a score greater than 15 get rejected. 

Configure spam filter

Use ``uberspace mail spamfilter`` to configure the filter for your account:

.. code-block:: console

  [eliza@dolittle ~]$ uberspace mail spamfilter status

  [eliza@dolittle ~]$ uberspace mail spamfilter disable

  [eliza@dolittle ~]$ uberspace mail spamfilter enable

We add the score to the mail header: ``X-Rspamd-Bar``, ``X-Rspamd-Report`` and ``X-Rspamd-Score``.
