This is one of my latest pet peeves. Can you imagine how much time was spent
writing the scripts just to make this possible? And all of that could have
been avoided by merely upgrading sendmail to use SMTP Auth. What I don't
understand is why SMTP Auth isn't totally widespread yet. Almost every major
email cleint out there supports this protocol... why bother with stupid
shenanigans like this?

We had a verizon customer who ran into this problem. Now they buy DSL from
us :)
