Just curious - has the idea of doing on the fly compression at the ESMTP
level ever been considered?
aarrgh. SMTP is already complex enough. the last thing I want to see
is more complex MTAs adding more failure cases.
I was thinking in terms of an ESMTP extension. In any event, by your own
admission, doing it as a MIME type would break a lot of software at the end
points. At least this way it is only attempted between mutually consenting
MTA's and is transparent to the end users.
