Why is it that every company out there allows connections through their

think of would be traveling folks that need to VPN or something, which
could be permitted in the Firewall, but WHY WIDE OPEN ACCESS? We still
seem to be in the wild west, but no-one has the [email protected] to be braven and
block the unnecessary access.
I assume you want this:

Most "unnecessary access" I see seems to be coming from US-based IP addresses anyway. A Great Firewall Of USA would certainly reduce the amount of spam I get :)

Hear Hear!
It'd be amazing how much easier my mail handling life would be if I could blindly drop * without worrying about collateral damage.

(Some years ago I had to ring an ISP in the US - and i'm in NZ - and ask them by _phone_ why they appeared to be filtering connections from here to their web server, despite the fact we were one of their customers. Turns out that they had inbound filters applied to 202/8. Whoopsie?)
