Assuming that no content_filter is configured on this machine: 1) Set a filter action in an access map for mail from 127.0.0.1: /etc/postfix/main.cf smtpd_client_restrictions = check_client_access inline:{{127.0.0.1 = filter smtp:[192.168.1.5]}} 2) Set a content_filter option for /usr/sbin/sendmail submission: /etc/postfix/master.cf pickup .. .. .. .. .. .. pickup -o content_filter=smtp:[192.168.1.5] Otherwise, this may be a job for http://www.postfix.org/MULTI_INSTANCE_README.html Wietse
