Does qmail support VRFY user?

Why do I always get 252 when I use VRFY?

qmail doesn't implement VRFY because (1) qmail's modular design makes
it impractical, and (2) VRFY makes it easy to validate e-mail
addresses and local accounts--information that crackers and spammers
like.

It always returns "252 send some mail, i'll try my best" to clients who
attempt to use VRFY, whether the user exists or not.
