Olá Comunidade! Após instalar o Discourse, estou com dificuldades na configuração de e-mail. Fiz a configuração necessária com o Mailgun. Enviar e-mail para [admin@domain.com](mailto:admin@domain.com) do meu [mail.google.com](http://mail.google.com) (gmail normal) está funcionando bem. Mas quando o uso com a configuração do app.yml, recebo o seguinte erro e não recebo e-mail. É o primeiro e-mail, não consigo me inscrever no meu fórum.

**Acho que é devido à autenticação simples. Li isso em um dos tópicos. Mas não sei a solução.**

app.yml

Ok, encontrei a solução. Eu estava usando o servidor US do Mailgun, mas na verdade é EU. Então foi um erro.
