    Default Missing X-Original-to: and Delivered-To: headers

    Hi all,

    In an effort to give my users better filtering options, I need to be able to identify who a message was actually intended for.

    I have added "enable_original_recipient = yes" to postfix's
    and that seems to add the users address to the Received line - like this:

    Received: from ( [])
    by (Postfix) with ESMTP id D276B6EC030
    for <>
    But it doesn't add an X-original-to or Delivered-to header line.

    I can probably live with the address at least showing up in the Received line, but the problem I run into is when a message is sent to multiple BCC users.

    For example, if I BCC a message to user1, I can see in the Received line of the header. BUT, if I BCC a message to user1 and user2, there is no user information at all...

    Received: from ( [])
    by (Postfix) with ESMTP id C4E156EC030
    All I see in the header is:
    To: undisclosed-recipients:;

    This is of course a problem because several users may have subscribed to the same mailing list that hides their addresses. The ability for the users to filter on their mail is lost.

    How can I get the X-Original-to and/or the Delivered-to header lines to appear in zimbra messages? The postfix documentation seems to indicate both of these should be added by default, and yet with Zimbra, neither of them are present.

    I can see the "orig_to" data in the postfix log for each message, so there must be a way to get this envelope data into the header.

    Any ideas on if this can be done, and if so, how?
