Please advice:

KMail when replying sets header "References" in which it puts msg-id of the
original message (i.e. of message to which we reply now).

Pine sets the same thing in "In-Reply-To"

Question:
1.) Should I add the header "In-Reply-To" with original message ID (clone
"References") as Pine does? Gnus v5.5 does it this way:
[In-Reply-To: Sven Radej's message of "Wed, 9 Jun 1999 15:15:46 +0200"]
Is this wrong? Is it important after all?

2) I saw that some mails have more references in "References" header. Where to
they come from? I mean you can reply to only one mail at a time.

3) I have reason to belive that "X-Loop" should in no circumstances end in To:, 
Cc: or Bcc: field. Am I right?

I am looking for sponzor to reward people who answer correctly to my questions
;-)
