Hi, I thought I understood how to block a specific domain from being able to send mail to users on my server, but I must be doing something wrong. In main.cf I have:
check_sender_access hash:/etc/postfix/sender_access, check_client_access hash:/etc/postfix/client_access among others, in the smtpd_recipient_restrictions section. In client_access I have the domains that should be allowed: mail.mydomain.com OK In sender_access I have a list that should be blocked: .domain1.com REJECT .domain2.com REJECT I've regenerated the postmap and reloaded postfix, but the mail still comes through. What am I missing? Maybe I don't understand the difference between check_client_access and check_sender_access. Thanks, Alex
