#14269: smtpd now conforms to the RFC and requires HELO before MAIL.

This is a backward incompatible change, but since it is an RFC conformance bug
and all real mail servers that I know of do conform to the RFC in this regard,
I believe it is an acceptable change for a feature release.

Patch by Jason Killen.
