I think you're misunderstanding how pipelining works. It just lets you send the MAIL FROM and RCPT TO commands all at once, and then check the responses when you send DATA. The server still sends back the exact same list of responses to each command. I suppose if it rejects the MAIL FROM you might leak something by sending the RCPT TO and DATA which will also be rejected, but so what?
