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.
