Dear all, I found that a lot of spam is using recipient email address as the sender. (from a...@internux.co.id to a...@internux.co.id, or from i...@apache.org to i...@apache.org).
Since if we mail to our self, usually we have very low score, I hope it is save to give a BIG score (probably 2 or 3). Is there a hint how to make this custom rule set?
