I have a domain with several users/email addresses, ie [email protected] I have forwarding setup so that any unknown email is forwarded to [email protected]. I previously had two other users who were removed from my system now their emails are forwarded to [email protected]. I can't seem to find a way of blocking or rejecting emails coming to these addresses. I am using postfix as the mail server. Thanks in advance for any help
Thanks Till for your reply. I have added Code: [email protected] REJECT Address not known at this server to the bottom of /etc/postfix/access I have also added Code: smtpd_client_restrictions = check_client_access hash:/etc/postfix/access to main.cf I have run Code: postmap /etc/postfix/access and restarted postfix but the email address is still forwarded to my address Any further help is apreciated

Looks ok. I think you should rather add something like Code: check_recipient_access hash:/etc/postfix/access to smtpd_recipient_restrictions and comment out the smtpd_client_restrictions line.
