I will gladly solve the RIGHT problem. The fact that I'm here looking for guidance should demonstrate that I'm looking to do exactly that. Unfortunately, I can't simply put "DO NOT forward SPAM" in my main.cf and have it work. ;) After reading through all the docs and various blog and forum posts, and making my best efforts at incorporating what I've learned into my configuration, it seems I'm still causing backscatter. That's exactly why I'm posting on Postfix-users - because I need a little more guidance than just "RTFM." :) So if anyone can help me with some SPECIFIC steps to take, I'd be very appreciative.
I posted it initially, but here again is my postconf -n output: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 home_mailbox = Maildir/ html_directory = no mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man milter_default_action = accept milter_protocol = 2 mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain, mail.$mydomain, www.$mydomain mynetworks = 127.0.0.0/8 myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix non_smtpd_milters = inet:localhost:20209 sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_data_restrictions = reject_unauth_pipelining, permit smtpd_milters = inet:localhost:20209 smtpd_recipient_restrictions = permit_sasl_authenticated, reject_unauth_destination, reject_unknown_recipient_domain, reject_unknown_sender_domain, reject_non_fqdn_recipient, reject_non_fqdn_sender, reject_invalid_hostname, permit_mynetworks, permit smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_sender_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unknown_sender_domain smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550 virtual_alias_domains = familyname.com virtual_alias_maps = hash:/etc/postfix/virtual I've been experimenting with various smtp recipient and sender restrictions, but clearly haven't got the right mix yet. Any specific guidance there, or anywhere else, is much appreciated.

No. Solve the RIGHT problem. DO NOT forward SPAM. Wietse
