You can reject the inbound message based on the HELO/EHLO if it is one of your domains. main.cf: smtpd_recipient_restrictions = ... check_helo_access pcre:$config_directory/pcre.helo_access, ... pcre.helo_access: /chez-vrolet\.net/ REJECT How can you be me? You should use WARN instead of REJECT and check the logs to make sure it will be the desired effect. It would help more if you showed logs demonstrating what you are talking about above. -- Duane
