Hi Bob; You are right. The problem is that I cannot implement both conditions in my antisspam proxy (ASSP). I can do the second condition but not both. So, currently, the appliance is allowing any mail to and from our recipients.
Your suggestions will almost surely solve my problem. I just forgot to mention that I want those who are allowed to receive to be also allowed to send to anybody. For that, I think will I need something like: smtpd_sender_restrictions … check_sender_access hash:/etc/postfix/sender-access … any other prameters?? Thank you very much. You gave me a big help.
