*blink* *blink*... Wait, what? When did *that* happen? :)

After digging into it, it looks like somebody *still* deserves to be smacked
around with a large trout, because there's no indication that that anybody
followed RFC6531 and negotiated SMTPUTF8, but just blindly spewed the UTF-8
(I've verified that at least 3 of the servers in the Received: chain do *not*
advertise the SMTP extension).  But then, this isn't my first rodeo (that
was back when Sendmail was still at 5.5mumble), so it's hardly surprising...

Guess I'll have to look at the exmh code and see what it would take to
start doing this right.  There's now enough of a pile of "needs fixing"
that I'll have to start doing serious exmh coding again, it seems...
