We have a spam blocker that sits on the Internet and forwards clean mail to our Exchange server. The MX record points to this IP, but we are still getting a lot of spam that never passes through our spam blocker. I have confirmed that it is not an internal spambot.
Question: How do I configure the ASA to only allow the Spam blocker IP to send mail to our internal network?
