   GREYLIST is a SMTP extension to formalize the widely supported
   Greylisting mail filtering method and to help support SMTP rejected
   transports by following a new formal structured 4yz server temporary
   rejection response by including a "retry=time-delay" tag string which
   SMTP clients can use to optimize the rescheduling of the mail
   delivery attempts.  With adoption, network overhead reduction in
   wasteful mail delivery attempts will be realized.

I would like to extend my grateful appreciation to the interested parties, onlist, offlist and lurking members of the Greylist-user support group, who provided input and assisted with the new draft. Thanks.
