一、配置postfix

　　vim /opt/postfix/conf/main.cf

　　smtpd_restriction_classes=smtp_acl

　　smtp_acl=check_sender_access hash:/etc/postfix/sender_list,reject

　　smtpd_recipient_restrictions = check_recipient_access hash:/etc/postfix/recipient_list, reject_non_fqdn_recipient, permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination, reject_unlisted_recipient, reject_invalid_hostname, reject_non_fqdn_sender, permit

二、配置sender_list

　　vim /etc/postfix/sender_list

　　eric@domain.com OK

三、配置recipient_list

　　vim /etc/postfix/recipient_list

　　all@domain.com smtp_acl

四、转换sender_list与recipient_list

　　postmap hash:/etc/postfix/sender_list

　　postmap hash:/etc/postfix/recipient_list

五、重新读取postfix配置

　　postfix reload
