Filtering mails

We filter incoming mails with Rspamd which uses multiple 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:

[eliza@dolittle ~]$ uberspace mail spamfilter status

Header

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