Spam Filter

Rspamd checks every incoming message and gives it a score: the higher, the more likely it is spam. What happens to the spam of each email address is chosen on the address's Spam Filter tab.

Switch on the server-wide spam filter

When off, no message is marked or rejected as spam; the signing of outgoing mail (DKIM) keeps working.

Spam from score *

Messages with this score or more are treated as spam (moved, marked or deleted per address). Lower = stricter. Default: 6.

Reject from score *

Messages with this score or more are refused by the server (the sender is told). Default: 15.

Greylisting

A suspicious message (score 4 or more) from an unknown server is accepted only when that server tries again a few minutes later: spam programs usually do not.

Train the spam filter from the messages users mark as spam or not spam

A message moved to the Spam folder (or marked with the Spam button in webmail) is learned as spam; a message moved out of it (Not spam) is learned as not spam. Works with every mail program.

White list

Senders never treated as spam: addresses (name@example.com) or whole domains (example.com), one per line.

Black list

Senders whose mail is always rejected: addresses or domains, one per line.
