Bug - In-Reply-To and Reference is lost in header when replying a second time



  • Procedure

    1. Incoming email
      I get a new email that I have not seen before.

    2. I reply
      When I reply on the email from step 1 I can see that “In-Reply-To” and “References” is added in the header of the email.

    3. I reply again
      I reply again by clicking on my reply email in step 2 above found in my Sent folder. Now “In-Reply-To” and “References” is lost from the header.

    Question
    Is this correct way or is it a bug that “In-Reply-To” and “References” is lost when replying a second time on a email found in my sent folder?

    RFC 5322
    RFC 5322 talks about this in section 3.6.4. I do think it says these headers should be preserved.

    WebApp: 3.5.1.2091+1151.1
    Kopano Core: 8.7.80

    Hi @Blinkiz ,
    if you look into your sent items you will notice that your sent items do not have headers at all (hence there is nothing to reference to).



  • Hi @fbartels
    And is that a bug or by design?

    My other email servers with thunderbird + dovecot/imap is not losing the header information.
    In my opinion at least “In-Reply-To” and “References” should be preserved so I get the correct tree structure of a conversation for myself and the user on the other side.


  • Kopano

    @Blinkiz that is currently by design



  • I read more in RFC 5322 and this is a bug in Kopano Core.

    The “In-Reply-To:” and “References:” fields are used when creating a reply to a message. They hold the message identifier of the original message and the message identifiers of other messages (for example, in the case of a reply to a message that was itself a reply). The “In-Reply-To:” field may be used to identify the message (or messages) to which the new message is a reply, while the “References:” field may be used to identify a “thread” of conversation.

    Happy to help out so Kopano becomes better. Have a good day :-)
