Thanks for the response and the suggestions. I had another task on my TODO list that required adding a header based on final recipient; using a transport map worked great for that task. In particular I could see the log entries show that the new transport was being used as expected. I tried a similar approach here and haven't had any luck yet. It's like none of the recipient virtual aliases that I've listed on the lhs are matching. Has virtual alias resolution already completed leaving me with the final recipient? Is that the value I have to use on the lhs? In master.cf, I added this since the final delivery is via LMTP: strip-automated-headers unix - - - - - lmtp -o syslog_name=postfix/strip-automated-headers -o lmtp_header_checks=regexp:/etc/postfix/strip_automated_headers.conf,regexp:/etc/postfix/header_checks.conf which is a copy/paste of the existing lmtp transport with a new name and two passed options (should be seen as three lines with leading spaces for the options). When I didn't get any activity in the mail log for that transport I tried it like so just to be complete: strip-automated-headers unix - - - - - smtp -o syslog_name=postfix/strip-automated-headers -o smtp_header_checks=regexp:/etc/postfix/strip_automated_headers.conf,regexp:/etc/postfix/header_checks.conf Anything obviously wrong with what I've tried? Thanks.
