He says, and has never said, anything of the sort.

Don't forget that I've been with Exim since more or less the start, and
that my memory is that of an eliphant.

What Phil says/said, that many MTAs can get broken by it.

In the mean time, Sendmail with 8-7 bit translaton has appeared, and
most other MTAs apart from Erfc1652xchange are disappearing. Read, mark,
learn and inwardly digest rfc1652.

Excuse me dude, but what do you know about "the rest of the European
community"? I know a lot. And it uses Sendmail 8-7 bit translation, for
the most part.

Just telnet to port 25 on some European mailserver or another and ehlo.

My ISP, Demon.nl, has never heard of 'ehlo'. It cannot translate 8-7 bit
mime. Basta.

He is not.

Perhaps you mean 8-bit transparent. I.e. no translation.

Trouble is, that most "proper" (not English, which keeps cadgeing off
American) European languages use above-ASCII code (look at ISO-8859).

Ermmm Demon cuts out 8 bit transparent. Basta. Phil says it does!

No. f.ex. dagbladet.no does an mx lookup on billy.demon.nl and gets
Demon's mailserver. Demon's mailserver accepts (which it shouldn't
according to rfc1652) 8 bit shit for Billy and cuts out all 8-bit stuff.
I.e. Norwegian letters.

The point is, this is am MTA that no-one else in Europe is using. It's
CRAP. It's called mmdf.

Yerrrrs, but this is what is called "quoted printable" and is 7-bit. So
no 1nder. Now ssh to a Norwegianj mail server and use Mutt or Elm or
something on THAT server. Find a Norwegian or Danish friend or
something. Then try it again.

No goose, this is for real.

Dman, I've been in this business since 1997. Used Exim since then.
Believe me ...

Yep. Do you want lessons in Norwegian, so that you can teach a couple of
hundred thousand of the most talented IT people in the world to do it
your way?
