*Rspamd.
Both of these will assign a 'spam score' to the message. We will then use the
===Spam score options===
Once a message has been processed by the spam engines the message will then be subject to one of three options:
* Non-spam - accept
* Medium-scoring Spam - accept, but marked with ****SPAM
* High=scoring spam - rejected if possible, otherwise handled as per medium-scoring Spam
The score at which a messages is marked as spam or rejected can be set on the Control Pages on a per-Mailbox or per-Domain basis. The default score to mark as spam is 5, and to reject is 20.
==Headers==
We add various extra headers to email regarding the Spamassassin and Rspamd scores and reports.
Here are some examples:
