No, I just get the text/plain part from the mailing list. And my email
client does not perform hard-wrapping but only soft-wrapping of text
messages. I.e. if I copy the text I won't get the newline characters.
So again, this  will work in kramdown.

Have you skimmed the article you linked to until the end? There they say
that you should wrap your text *before* sending, ie. you should
configure your mail program like I did with mine to wrap the text so
that there won't be any problem in any mail client! You could do this
with/for your users - then the sent messages will contain nicely
formatted text. The only problems that remains would be when quoting
another email...

As said above, just correctly configure the mail clients (if you have
access to them!).

There has been some discussion on this on the Markdown ML, for example,

Just tell them to use blank lines between block level elements and one
worry will just go away! As for the lazy indentation, I'm still
skimming the Markdown ML on this.
