in the business, we call this "tough noogies."

i've gotten very good mileage out of ssl-smtp, and out of "port forwarding"
so that my laptop uses 127.0.0.1:25 for outbound mail, which is actually a
(ssh-borne) tunnel to my home smtp server.

yes.  let me take this opportunity to thank you for your significant
contributions to smtp and of course rfc822.  i'm sorry that you have to
be hurt now.  but the design calls for a polite population, and while
that was true of the internet in 1983, it is absolutely not true today.
the nonpolite nature of the overall population means that you will have
to be hurt and you will have to change how you use mail in order to make
the pain stop.  there's a slight choice on the pain menu -- you can have
(A) an unusable mail system clogged with unwanted traffic such as spam
and viruses, or (B) a barely-usable mail system where everything you want
to do is less convenient because you have to use ssl-smtp and ssh tunnels.
either way you have to be hurt now.  and that saddens me, it really does.
