I just fear that it's a very small step to go from blocking known dialup
pools to blocking any IP that resolves to a pattern like
"1-2-3-4.example.net".  That looks like a dialup, and if it's a cablemodem
or DSL line who cares, that may as well be a dialup right?  After all, if
it were a true mail server that could be trusted it wouldn't have a name
that starts with its IP address, only dialups use those.
