First, read up: http://www.google.com/search?q=top+posting Then have another look at the documentation; http://www.postfix.org/postconf.5.html#internal_mail_filter_classes http://www.postfix.org/postconf.5.html#header_checks http://www.postfix.org/header_checks.5.html With 'internal_mail_filter_classes = bounce' and the header_checks, you might be able to redirect your message, feed it to whatever software generates the 'X-Mms-Transaction-ID' for you, and then reinsert it for delivery. If the transaction ID is the same for all messages it might even be as easy as using a 'PREPEND' or 'REPLACE'.
