1. Is the email an old template and that the new rules are actually going to be enacted?
2. Is this an email spam of some sort? Should I send a mail to the support email address asking what the hell is going on?
3. Why would anyone target my domain - it only gets about 10,000 uniques a day and just about covers my mortgage but no more?
[edit - changed wording in case I libel anyone]
it's likely that someone maybe trying to steal your domain. just make sure to lock your domain.
