We have two new contestants. MailerMAX from Lithuania makes an appearance solely due to having allowed in a group of Finnish spammers, some of whom operate more or less openly (because you can’t register .fi domains anonymously). These are the same bunch who gave MySMTP their #1 spot in June.

The mail from Green Arrow is a curious mix of U.S. political commentary and Scandinavian “you must have participated in an online competition to sign up” outright spam. Annika, are you listening?
