We understand what you mean. Just boss ask whether the change can be made. >>Whatever in-band signalling you might need should be something other than >>"Resent-From" (usually accompanied by Resent-To, Resent-Date, and >>Resent->>Message-Id). If we like to add line Resent-to: <OSU email address>, is it possible for Postfix? >> If the forwarding is via local(8) aliases, the "Delivered-To:" header may be >> something along the lines of what you're looking for. The forwarding is not in local aliases. We have 100,000+ forwarding accounts. It is tough to add so many forwarding accounts into 8 Postfix servers and keep real time update. >> There are also various extensions to Postfix to handle SPF and SRS. Would you please talk a little more about above topic?

"Resent-From:" is appropriate when a user takes a message delivered to his mailbox (possibly long after initial delivery) and resends it to another user (typically not an original recipient). It is not appropriate for simple forwarding to a recipient's mailbox. Whatever in-band signalling you might need should be something other than "Resent-From" (usually accompanied by Resent-To, Resent-Date, and Resent-Message-Id). If the forwarding is via local(8) aliases, the "Delivered-To:" header may be something along the lines of what you're looking for. There are also various extensions to Postfix to handle SPF and SRS. -- Viktor.
