    Thank you for posting here.

    It seems that this package does not provide the ability to distinguish between new email and reply email.

    I think it might be better to contact its author.

  • There are two ways that mail applications recognize replies.  One is by the present of "Re:" at the start of the subject line.  The rest of the line has the original subject.

    The other way is by headers.  Every message has a Message-Id: header.  The References: header is supposed to list the Message-Id values of the previous messages in the thread.
