Right. The point is that the Verisign SMTP responds with a fixed series of
reply codes (220, 250, 250, 550, 221).  So let's run that with 3 recipients:

220 snubby4-wceast Snubby Mail Rejector Daemon v1.3 ready
MAIL FROM..
250 OK
RCPT TO...
250 OK
RCPT TO...
550  User domain does not exist.
RCPT TO...
250 OK
DATA
221 snubby4-wceast Snubby Mail Rejector Daemon v1.3 closing transmission channel
<Connection closed by foreign host.>

Now what do you do, absent a 3xx reply to your DATA command?
