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@xxxxxxx>
      S: 250 OK
      C: VRFY Jones@xxxxxxx
      S: 250 <Jones@xxxxxxx>
      C: RCPT TO:<Jones@xxxxxxx>
      S: 250 OK
      C: VRFY Green@xxxxxxx
      S: 250 <Green@xxxxxxx>
      C: RCPT TO:<Green@xxxxxxx>
      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@xxxxxxxx 
According to 4.2.5 above, since Green@xxxxxxx 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@xxxxxxx (retrying if necessary) and bar.com (the client) SHOULD 
NOT attempt to retry delivery to Jones@xxxxxxxx Is this the correct 
interpretation?

[Again, I think that this is *not* the correct interpretation.]
