Of course it does not.  Your questions are welcome, even if they are
more Emacs- than Mailutils-related:)

In your .emacs you have:

(setq mail-default-headers "User-Agent: RMAIL; GNU Mailutils 2.1; GNU Emacs 
23.1")

The value of this variable is inserted into the headers verbatim, hence
the missing newline.

> How can I include a "newline" in the User-Agent header?

Add an \n symbol to the end of the above statement:

(setq mail-default-headers "User-Agent: RMAIL; GNU Mailutils 2.1; GNU Emacs 
23.1\n")

Then it will not be a header.  Headers are `name: value' pairs appearing
*before* the very first empty line.  Mail body is everything that goes
after it.  So, your question actually is: "can one set up the body of
the message before entering compose mode".  The answer is: yes, use
mail-setup-hook.  This hook is executed when you hit `C-x m' (or
whatever key binding you have to turn on mail mode).  It can be used to
insert any data both in the header and in the body parts of the message.

> can this In-reply-to header be customized?

Well, in Emacs everything can be customized:)  However, I wonder why do
you need to modify that header.  It does not seem a wise idea, because
the In-reply-to heaader is strictly formalized by RFC 2822, and adding
arbitrary data to it may misguide recipient mail software.
