The point is not to check whether or not n.o.thanks@microsoft.com is your address, but that it follows valid syntax. Users make mistakes - I just watched a customer this morning type name@domaincom instead of name@domain.com when entering his address. I've even seen users enter their names instead of email addresses when prompted for an email address. This happens all too often and can make database management a hassle. Checking the syntax first can make life a little easier for the DB guys.
