  SAML and SOML are underused on the internet, yet the equivalent
on BITnet is heavily used....
  Don't take them out of the spec: you may want them later,and a standard
way of doing them is desirable.

  VRFY is utterly necessary to postmasters, and is therefor mandated by the
Hosts Requirements RFC: finger is shut down on all too many sites, and so
vrfy/expn are required to verify adressees when mail goes astray.

  And HELO is the hook for stronger authentication: even now it and thge
recieved lines allow me to spot (poorly-)forged mail at a glance.

(small flame)  If you've implemented smtp, you should really know all that...
