According to CJK.INF, it's RFC 1521 and 1522: "MIME (Multipurpose Internet 
Mail Extensions) Parts One and Two: Mechanisms for Specifying and Describing
the Format of Internet Message Bodies," by Nathaniel Borenstein and Ned Freed,
September 1993.

Another relevant one is RFC 1468: "Japanese Character Encoding for Internet
Messages," by Jun Murai et al., June 1993.

CJK.INF has some details on how MIME encoding is performed, and lots of
other useful info. You may want to take a look at it:

	CJK.INF Version 2.1 (July 12, 1996)

BTW, TLUG is listed in the Appendix, under "Mailing Lists":

	TLUG (Tokyo Linux User's Group) Mailing List

It's the later. Running the ML with Listprocessor, there's not much to
be done at the server's side. It depends mostly on the subscriber's set
up being MIME-complaint.
