Hi everyone,
I'm having some trouble with iptables blocking incoming mail; I'm not
sure where it's getting blocked, as I'm able to telenet to port 25; any
idea what is wrong with my rules? Thanks.

That looks a bit loose to me, but I don't see why smtp wouldn't be getting
through. What makes you think it's the firewall? If you stop iptables, does
mail come through?
