[issue14269] SMTPD server does not enforce client starting mail transaction with HELO or EHLO

Ok I think this quote from the spec referenced pretty much sums it up. 

"The NOOP, HELP, EXPN, VRFY, and RSET commands can be used at any time   during a session, or without previously initializing a session.  SMTP   servers SHOULD process these normally (that is, not return a 503 code) even if no EHLO command has yet been received; clients SHOULD open a session with EHLO before sending these commands."

All in all either way fits the spec, choose your favorite.
