That will never fly at python.org:  there's too much spam coming in for
anyone to deal with (or so I've been told -- I believe I get more spam at
home, but only an infinitesimal percentage of the virus email python.org
gets).  Indeed, Greg bounces lots of spam at SMTP *connect* time, without
analyzing it any deeper than seeing that it uses a character set that's out
of favor.  A Reject response should make its way back to the sender then.
If not, ya, the email is lost.  Put a specific price on that, because it's a
tradeoff, and "never" is too costly in other ways to tolerate.
