RFC 5321 section 4.5.1 states VRFY should be implemented in order to be
considered an RFC 5321-compliant implementation. But, in section 3.5.3
paragraph 2 it states that if the actual verification was not performed but
syntax was checked similar to RCPT, then the response code should be 252.
So my purposes for providing the plumbing for VRFY are:
1. Provide a basic, valid implementation to be as RFC 5321-compliant as
2. Let users know the command is there so that it can be reimplemented as
they build their solutions.
