I did say I was "wary", not that I am totally against making any
specific changes.

What is gained? What do other people on this mailing list think?

I have been told that it is a very bloated thing. I have not looked at
the RFCs myself yet, so I can't judge.

Exim is, and always has been, 8-bit clean. I believe the continued
insistence on 7-bit standards is really silly. TCP/IP has always been an
8-bit transport. (Here I am in complete agreement with Dan Bernstein.)
"Just-send-8" has more success than munging the message in any way. If
you set "accept_8bitmime" Exim will "offer" 8BITMIME in the ESMTP
greeting, but it won't do anything other than just send the message it
gets.
