%description
This filter implements the Rspamd protocol and allows OpenSMTPD to request an
Rspamd analysis of an SMTP transaction before a message is committed to queue.
The filter currently supports:
* greylisting
* adding X-Spam related headers to a message
* rewriting Subject headers
* DKIM-signing messages
* using Rspamd-provided SMTP replies
* allowing Rspamd to add and remove headers
