Yet Another Article That Wants To Reinvent SMTP.

Or, as I like to put it, "Slow news day".

SMTP "trusts too much".

That's like saying "TCP/IP trusts too much".

Someone's not reading the damn acronym. Simple Mail Transport Protocol.

Note the words "Simple" and "Transport".

SMTP only cares about two things: Are you allowed to connect to this server? and what would you like to send?

Security and content filtering is SEP, and rightly so.

Well, what do you expect from an outfit called news.com.com?

Note for Norm: Email clients wouldn't necessarily have to be rewritten; any new protocol could emulate the old one sufficiently to negate this requirement.
