I *think* he meant '..ever filter on and stay in the business of transferring
maessages reliably'.
Another poster's remark about 'real cert' doesn't apply either - these are
nearly always self-generated, self-signed, and not checked against a CA, public
OR private at either end.
Requiring matching PEM certs - as for a corporate intranet - is a different
application.
Spealing of which - TLS for submisson, TLS for POP/IMAP, and TLS for MX - MX
does give nearly end-to-end protection between/among corporate servers.
Providing they - and the MUA boxen, have at least some level of physical
security. Better than nothing, anyway.
Not much help for off-net correspondents, of course.
