Doesn't this look a bit odd? I haven't clicked on the link by the way, but I assume that it just confirms that my account is active and will add me to a spam list. The reason I received this email was because I emailed the SecurityFocus pen-test mailing list - well, not the reason, but the method by which my email address was obtained. As this email looks slightly fishy, I thought I'd post it here. I've never received a Brazilian email before

Thanks,
