But it's harmless, and trivial to implement a version that replies 252 to everything so it's more trouble than it's worth to take out.
Proposal from IETF 113 is no change in base spec, but can discuss on mailing list the idea of putting extra text in A/S
Separately, there was a suggestion to register VRFY with IANA. It used to be a separate extension and it would be good to have it in the IANA registry.
Registration of VRFY with IANA added in -11.
Nobody implements VRFY any more other than by always responding 252. It seems pointless still to require it.
