We deployed some little fixes (and you probably didn't even notice the deployment; what is a good thing, since we strive to make such updates totally seamless). Most important from them is that we fixed how the SMTP settings are populated. That means that if you want to send e-mails from your tenant (like from a contact form or to get notifications about new comments to your blog), it will work now.
Now if you wonder: "I wanted to try this a day ago and it didn't work, interesting that you fixed it now." - yes, you! We made it because we noticed you had trouble :-).
