So contact your ISP and have them assign you rDNS for your IP that
doesn't resolve to

durham-ar1-4-64-253-233.durham.dsl-verizon.net

AFAICT, it's no different from the tens of thousands of open proxies
running on all the other DSL/Cable/dialup hosts out there. And though
I, too, lament the passing of the old 'Net with all of its trust and
gentle ways, I also lament the massive waste of time spent fighting spam.
And I'll take what measures I can to prevent that waste.

Cheers,
Steve
