VRFY is pretty useless by now because many sites disable it.
Postfix invokes smtpd_recipient_restrictions to make the reply
similar to that of RCPT TO (no point to have VRFY reply with 2xx
when we already know that RCPT TO would reject the same address).
However, that similarity broke long ago with the introduction of
smtpd_delay_reject=yes, and with client/helo/sender restrictions
in smtpd_recipient_restrictions.

That understanding is not supported by RFC 821, 2821, ...
