I'm probably messing with something I shouldn't be here - but is there a
way to have rejections based on a dynamic real-time blacklist (DNS lookup)?
As an example - I may have a RBL I maintain for blocking e-mail
spammers. As I have no earthly reason to accept connections of any kind
from these locations - I'm curious if I can block them at an IP level -
before they ever reach my mail server.
