I recognize that there is a problem with DNS that has potential for abuse,
but I seriously question whether the mail transfer protocol is the
appropriate place to deal with it.
Is this problem, by itself, justification for the additional overhead of
X.509 authentication for the *receiving* MTA as a requirement in the mail
transfer protocol? I tend to think it's a problem that should be dealt with
in DNS.
