RFC2554. Works very well for me; people can connect from 
anywhere that doesn't have port 25 filtered or they can connect on
port 587, which is meant specifically for authenticated SMTP
connections.
Supported by all major e-mail clients, except for Outlook/OE 5.0, and
even then only if they are using a specific version of INETCOMM.DLL that 
has a bug that causes it not to send authentication; upgrading to 5.5
fixes
that.

Sendmail, Exchange and a number of other mail server products now offer
RFC2554 support.
