A friend of mine recently changed his e-mail address, so I deleted his old one from my address book and replaced it with his new one. Simple as that, right? Wrong. Now the old e-mail address keeps popping in mail whenever I enter his name and hit enter. Mail does that (auto-filling) for all recently used e-mail addresses and address book entries, but worst of all is, it keeps selecting the old address as the default one? So I find myself sending messages to this person, only to discover a 'address not in use' response in my inbox a few seconds later. Any way to delete an address from the recently used database or at least change the address book entry to be the default one?
