Another thought on the problems of not transiting to MIME:
The possible decision of people to go with 8bit in place of MIME is a
non-starter. The main reason is that doing so, without also converting
to MIME, is to continue sending unlabled objects of various content
types.
I must observe that just sneding 8bits has never been a solution to the
problems of sending different character sets in RFC822 mail bodies. It
will only get you some small efficiencies in sending unlabelled objects.
It is not a good solution. It will not be a good solution tomorrow
either, or next year, or the year after that...\Stef
