Spam scoring for outgoing mail
Emailit now scores every outgoing message with a spam filter before sending and holds messages that score 7 or more.
Updated Sep 27, 2026
Before delivery, Emailit checks each signed message with Rspamd, an open-source spam filter. Messages that score 7 or more get the status held instead of being sent, so mail that would likely land in spam doesn’t hurt your reputation. If the spam filter is unavailable, mail is sent without a score rather than delayed.
To release a held message, fix its content and retry it. See Spam checks.
