Hi all, We have a spam problem. We get a lot of emails, where the sender (MAIL FROM) address is equal to the receiver (RCPT TO) address. When I look at the "Received:" header field, the IP address of the server it's coming from, is not our mail server.
I would like to know if there is a way to block (or tag as spam) those emails, either with Postfix, SpamAssassin or Procmail, if they don't come from our mail server? Thanks, Chris
