I have a xeams instance set up as a Spam Firewall with all other server functions disabled.

I am seeing incoming score items like this : -1000 Sender has been authenticated by SMTP server.

As far as I can tell this is something that only applies to outgoing mail - it looks like it is considering relaying this back out even though SMTP server/relaying is all disabled.

I would like to completely disabled this item as it is always bogus but I can't find it in any filters or other settings.
