I sent an email to your main email address, I'm repeating the information here.
Our forum mail service, Mailgun, attempted to deliver the emails to you. Your email host sapo.pt bounced the messages with the error
DNS temporary failure at return MX check, try again laterErro temporario de DNS na verificacao do MX, por favor tente mais tarde (#)
(technical error code: 421 DNS temporary failure at return MX check, try again later (#4.3.0))
This means your hosts's mail server mx.sapo.pt was unable to find an mx record for our mailgun server mg.getsol.us. I can get the mx records, they definitely exist. I've double checked our server setup, and everything looks good. Others, including myself, are receiving emails from the forums.
Please try resetting your main password again. I recommend only trying once. If you still don't receive the email, reach out to the support folks for your email host.
Good luck, and let us know what happens.
