Gone Phishing

On returning to work after the bank holiday I found that my email inbox was full of phishing attempts. Unfortunately for the phishers, I have no accounts with the banks I was being phished by, so it was easy to delete them. But I have to ask, why are phishing scams so random?

Furthermore, why don’t email phishing filters put on a big notice “DODGY” on such emails? They seem to recognise the links as false, so why can’t they be a bit more proactive at marking the messages themselves? It would also be nice to be able to tell your email client which banks you bank and web services you use with so at least they could ignore the false ones.
