To their (partial) credit they are also supporting a new email header : Require-Recipient-Valid-Since: via draft-ietf-appsawg-rrvs-header-field The idea of this header is that it will allow a sender to control that a user will only receive an email if that email address was valid before a specific date, thus at least stopping someone from using a recycled account to carry out a password reset on another service. Facebook at least is already sending this header on all emails. Overall this is nothing new - Hotmail has been doing the same thing for years.

You can do the math how this might affect you, your services, and your users, if you have those.
Will people *ever* start listening when we tell them how Bad an Idea something is? The RISKS are endless...
