Converting SMTP command line options into message headers requires an SMTP-based filter, for example, smtpd_proxy_filter. See: http://www.postfix.org/SMTPD_PROXY_README/html The reverse, conversion from from message headers to SMTP command line options, also requires an SMTP-based filter. Postfix strips SMTP syntax while receiving mail, and adds SMTP syntax while delivering mail. The rest of Postfix knows nothing about SMTP. Wietse
