You're missing the context. We were talking about how the messages have
to be formatted, not about how they are transferred.

You missed my point.

The contents of each message is text.
Plain ASCII text.
ALL 'attachments' end up as part of the 'DATA' portion of the message and
are transmitted as plain ASCII text.

If you want to communicate most reliably, you will stick to plain ASCII
text. If you want to communicate most economically, you will stick to
plain ASCII text. If you want to communicate most safely, you will stick
to plain ASCII text.

Any encoding, such as mime and HTML simply add hazards and complexity.
They add 'bling' but they most often prove to be an unnecessary and
unneeded conduit for infection and a reliable sign of spam.

That is not to say that they are not valuable for languages that can not
be represented in plain ASCII, but there is no reason for me to need to
send or receive such messages.

Ah okay, so your reply was actually to something different than what you
quoted. However, the complexity added by MIME is tolerable in my
opinion. Almost every invention makes things more complex.

I admit that HTML does add quite some complexity, which is quite more
than that added by MIME. But other standards are much more complex, and
you really shouldn't always take Microsoft's implementations as
examples.

You don't need MIME for messages in other character sets than ASCII.
