ok, I'd rather have a little bit of mail lag if it means I stop getting spam mail and the only people taking a hit would be the gold sellers, it seems like a little bit of inconvenience for a lifetimes worth of peace, and let's be honest the only in game mail you're likely to receive is from the gtn at later levels, just straight trade with friends and guild members, if they have the time to code in 50 million companions you'll never use than they can easily implement a privacy mail function.
