I was wondering on the specifics. You if you can't send email to a UK business address unless you have permission, and you can't send unsolicited email to an address in Italy at all, does that mean no-one can send email between the UK and Italy without calling to see if it's OK first? You can't send an email asking for permission, after all.
Just taking it to the least level of absurdity.
Ignore me, I'm just enjoying watching the slow demise of email...
