Road Runner 550 Unable to Relay Error

[Mike Coleman]

For what it's worth, I'm on RR and have my own domain.  That domain is hosted
at another ISP and I send my outgoing email straight to them.

I use RR strictly as a fast pipe.  The problem you're having (as well as some
I've had) may indicate that they're not able or willing to be a good provider
of other ISP functions.

Our local university offers a three hour course, College Algebra, which covers
"elementary algebra, solution of equations, functions, exponential and
logarithmic functions, inequalities, systems of linear equations, equations of
second degree and their graphs, binomial theorem, complex numbers, and
polynomials".  They also offer a three hour course which covers Office 2000.
Does this mean that Office is as simple to learn as College Algebra?
