Like many people, my residential ISP blocks port 25 outbound, and port 587 was either blocked or not working on Mailinator any more. However, an Nmap scan of [mailinator.com](http://mailinator.com) reveals that port 2225 is open for SMTP traffic. After changing my notification settings to [mailinator.com](http://mailinator.com) port 2225, notification emails work.
