I regularly receive emails from domain registrars I use asking me to confirm my email address to stay in line with ICANN requirements. Typically, I either ignore these emails if I know my information is up to date, or I will click the email to confirm when I know the email is legitimate. For instance, I regularly receive Whois update emails from Network Solutions following NameJet auction wins.
None of these types of emails request a payment of any kind, and they are always (as far as I can recall) from the domain registrar of record rather than ICANN.
Yesterday afternoon, I received the first email like this purporting to be from ICANN. The email instructed me to confirm my email and make a payment. It had the ICANN logo on the top of the email, but the email was clearly not from ICANN.
