What you really want most probably isn't ESMPTPS - unknown
stranger sends mail, adding encryption won't help you. You
want "reputation", something telling you that the unknown
stranger is a good guy / new kid / known troublemaker.
For better ideas in this direction see MTAMARK, CSV, and the
HELO part of SPF. For products in this direction check out
senderbase / ironport / spamcop.
Bye, Frank
im primarily talking about authentication, all other considerations like
strong encryption secondary, for now...
btw, spamcop and colleagues complaining more and more about perfectly
forged headers... so these systems will fail soon.
