This client server handshake must hold S: 220.* C: HELO foobar.com S: 250.* C: MAIL FROM: <[EMAIL PROTECTED]> S: 250.* C: RCPT TO: <postmaster@localhost> S: 250.* C: QUIT S: 221.* Where C is client data and S is server resonse. .* is regex pattern. Recieving mail servers may do this loop back test to validate mail server. Filters out at least some of the worst spammers.
