Use a check_recipient_access regexp: or pcre: map. Off the top of my head: ( s/example.com/your-domain/) IF /@example\.com$/ /some-allowed-pattern/ DUNNO /explicitly-bad-pattern/ REJECT invalid recipient detected ENDIF > So, how do I get Postfix, my MTA, to put the envelope address into > the headers? Use a check_sender_access map (under smtpd_data_restrictions so you don't get multiple headers). /^(.*)$/ PREPEND X-Sender: $1 See the postfix docs or the postfix-users list for more details. -- Noel Jones
