When the outgoing message is ASCII only, all ways I tried to enforce
quoted-printable encoding failed to work. I have in my .emacs:

 (setq mm-coding-system-priorities '(iso-8859-1 utf-8))

and I tried enforcing quoted-printable with:

 (us-ascii . quoted-printable)

in mm-body-charset-encoding-alist. Still, in the case I posted, the ">"
and the mail itself are sent without using quoted-printable encoding.
