I've never been able to leverage SMTP AUTH to bypass greylisting w/ 
sendmail.  Not sure if that's the intent of the original request.  Some 
folks suggested running sendmail on a separate port w/ a different 
config that required SMTP AUTH and bypassed greylisting in the config 
but I never did that.

I'd love to have a solution.
