Functional development setup without SMTP?

[decentral1se]

Related to #821, would it be possible to configure a test email server for development mode? Something like https://mailcatcher.me. In this way, emails would be logged to the terminal and not cause the following error. It can't send any email but I haven't configured it yet. This makes testing and working with a timeoverflow setup that has no SMTP configuration not really workable. You can't create any new users without dropping into the command-line?
