=09Who says the recipient's mail server has TLS capability? It's=
really the
same problem as what happens when joe@aol.com wants to send email=
with his
personal origin address from his work machine which has nothing=
to do with
the AOL network. Except it's a bit harder to solve because in the=
AOL case,
AOL could just offer some solution. The problem occurs when I=
have an
@aol.com email address but don't trust AOL to handle my outbound=
email.
=09Again, though, it's reasonable to say, "If you don't trust AOL=
to handle
your outbound email, then don't use an @aol.com address. You have=
to trust
them for inbound anyway."
