Xie, Wei: > Here we have a question about postfix. When the message passes by > Postfix, can Postfix automatically add line "Resent-From: <OSU > email address>" in the header?
Postfix it will add a "Delivered-To: <OSU email address>" header, when it delivers mail to a non-virtual alias, or to a user. If the user forwards the mail with a .forward file or with a procmail rule, then the forwarded message will contain that "Delivered-To:" header. Other forms of Postfix email forwarding silently replace the recipient address, without adding information to the message header. As noted in other follow-ups, Resent-from is not appropriate It already has a meaning that is different than what you request. Wietse
