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?)
