Re: STARTTLS & EHLO

[Tony Hansen <[e-mail]>]

If this is the interpretation that we gain consensus on, that it means
"start over from scratch", it might as well also say that it

	SHOULD only be executed immediately after the initial EHLO.

The only possible exceptions to this rule would be for verbs that don't
affect the state machine, such as VRFY, EXPN, HELP, NOOP.
