This might be a usefull line. You might blacklist hotmail email where
the source IP adres lies in certain countries.
To the best of my knowledge several web based email servers use this or
a very similar header.
Combined with the chat I had about ASN detection we might write a custom
function to tacke this.
Another header that might help you a bit:
| To: undisclosed-recipients:;
Personally I let postfix reject messages with this header. It may sound
harsh but it kills a lot of nonsense messages.
