Howto configure sendmail SMARTHOST with authentication??

I need to configure sendmail to use SMART_HOST so my ISP, Earthlink, will not block my SMTP outbound traffic. They told me the name of a SMTP server to use in my define SMART_HOST. However, that SMTP server requires a login. When I configure SMTP on a mail client using that server the authentication is username =, and 'password'. Where do I put that info in the define. The only format I've seen is the one below:

define(`SMART_HOST', '')

How do I configure the login and password?

Thanks, that worked great!

I have the latest version of sendmail, so the second part of:
worked for me. Just adding the line to /etc/mail/access and rebuilding the DB solved the problem.

Thanks so much for all the help from everyone. Some of the mail things are a bitch to setup.

Thanks again.
