I believe that, not withstanding the VRFY, the "450 Can't send to him right

Darnnit! I screwed up the example (in several places). Let's try that again:
Take the following example:
S: 220 foo.com Simple Mail Transfer Service Ready
C: EHLO bar.com
S: 250-foo.com greets bar.com
S: 250-VRFY
S: 250 HELP
C: MAIL FROM:<Smith(_at_)bar(_dot_)com>
S: 250 OK
C: VRFY Jones(_at_)foo(_dot_)com
S: 250 <Jones(_at_)foo(_dot_)com>
C: RCPT TO:<Jones(_at_)foo(_dot_)com>
S: 250 OK
C: VRFY Green(_at_)foo(_dot_)com
S: 250 <Green(_at_)foo(_dot_)com>
C: RCPT TO:<Green(_at_)foo(_dot_)com>
S: 450 Can't send to him right now
C: DATA
S: 354 Start mail input; end with <CRLF>.<CRLF>
C: Blah blah blah...
C: ...etc. etc. etc.
C: .
S: 250 OK
C: QUIT
S: 221 foo.com Service closing transmission channel
So, the message was delivered successfully to Jones(_at_)foo(_dot_)com(_dot_)
According to 4.2.5 above, since Green(_at_)foo(_dot_)com exists, and foo.com
(the server) has sent back a 250 to the DATA command, foo.com (the
server) now has responsibility for delivering the message to
Green(_at_)foo(_dot_)com (retrying if necessary) and bar.com (the client) SHOULD
NOT attempt to retry delivery to Jones(_at_)foo(_dot_)com(_dot_) Is this the correct
interpretation?
[Again, I think that this is *not* the correct interpretation.]
