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?
