AuthSMTP is where you authenticate directly to the SMTP server rather than popping first and requires support from the mail client. I think Netscape and Outlook do this but it's still not too widespread. Another alternative is to check for a 'password' in the HELO which in many cases is easier to set (for example on Windows you would just put it into the domain name box in tcp/ip dns config).
