Yahoo (and now AOL) have changed their domain authentication policy so that emails are not allowed to be delivered if they are sent via a third-party application.
This is going to affect you if you have a website where your users can send emails from their own email addresses via your website and your website uses a third-party service such as Mandrill to deliver emails.
Read here how we dealt with this at Quillcards.
Interesting, thanks for sharing. There are so many changes to keep up with.
Like the way you explain things.

I read it and understood. Luckily for me, I don’t have to think about it. Over the years, I’ve had several Yahoo email addresses. There was a period, I think perhaps last year, when each and every one of them got hacked. Then they deleted all accounts they considered ‘inactive’. I just don’t bother with them anymore.
