The Compliance Filter can be used to set up rules, which will apply to incoming or outgoing emails. You can set up the filter from within the Control Panel in “Management > Email > Compliance Filter”. This service is part of the Hornetsecurity Spamfilter and will not be charged separately.
Identifying affected emails via Workspace
If an email triggers a rule, you will find “compliance-rule” as a reason followed by the ID of the Compliance Filter. You can locate the ID of the rule from the Compliance Filter list.
