Hi everyone, Could anyone please help me to explain where Mailman keeps record of who reply to a particular post? Thanks Nghia Simple answer, it doesn't. What made you think it did?

If you are wondering about how the archives know how to thread the discussion (for the threaded view), this is done by message headers in the email put in by the replying email program, which indicate the message-id (a unique identifier added to all emails by email systems) of the message it is a reply to.
