Olá, Acabei de instalar uma nova instância na AWS e quero configurar o envio de e-mails. Tentei enviar um e-mail usando o swaks a partir do host → ok Tentei enviar um e-mail de dentro do container (com swaks) → ok O comando que usei foi: > swaks -server \:587 -tls --auth-user \ --auth-password \ --to \ --from \ A seção correspondente no app.yml está assim: > DISCOURSE\_DEVELOPER\_EMAILS: ‘\’ > > DISCOURSE\_SMTP\_ADDRESS: \ > DISCOURSE\_SMTP\_PORT: 587 > DISCOURSE\_SMTP\_USER\_NAME: \ > DISCOURSE\_SMTP\_PASSWORD: \ > DISCOURSE\_SMTP\_ENABLE\_START\_TLS: true E estas são as últimas linhas do meu app.yml: ``` run: - exec: echo "Beginning of custom commands" ## Se quiser definir o endereço de e-mail 'De' para o seu primeiro registro, descomente e altere: ## Após receber o primeiro e-mail de cadastro, comente novamente a linha. Ela só precisa ser executada uma vez. - exec: rails r "SiteSetting.notification_email=''" - exec: echo "End of custom commands" ``` Então, na minha opinião, fiz tudo corretamente… Mas o que me intriga é que, ao verificar os logs, vejo o seguinte: ``` Delivered mail c73248c3-a56b-4100-a34b-63ad1eb3dab8@ (5275.2ms) Job exception: 504 5.7.4 Unrecognized authentication type ``` O estranho é que o \ é, curiosamente, o domínio do certificado que criei para a instância. Não sei como isso está relacionado ☹ Alguma dica do que eu poderia fazer? A última parte sobre aquele domínio é apenas um pensamento e não sei se representa algum problema. O > Job exception: 504 5.7.4 Unrecognized authentication type pode ser uma pista, mas, como disse… o swaks funciona perfeitamente. Obrigado e abraços, pessoal, ---

Realmente ninguém? … isso é ruim ☹ Estou sem ideias … ---

Você já tentou todos os passos mencionados aqui? > [@Troubleshoot email on a new Discourse install](https://meta.discourse.org/t/troubleshooting-email-on-a-new-discourse-install/16326): > > You just installed Discourse via [the install guide](https://github.com/discourse/discourse/blob/main/docs/INSTALL.md), but email doesn’t seem to work. Unfortunately this means you can’t log in as an admin to finalize the install. cry Let’s troubleshootize! Try the doctor woman_health_workerIf you run ./discourse-doctor it will check several ways that your mail configuration might be broken, and offer advice. Try that first.

Olá @rishabh, tentei tudo o que foi sugerido aqui, imagino 🙂 Existe alguma maneira de reproduzir exatamente como o Discourse tenta enviar e-mails? Quero dizer, não sou expert em Ruby, mas por acaso existem ferramentas que enviam e-mails pela linha de comando e que utilizam os mesmos mecanismos?.. ---

Não consigo resolver isso ☹ ---
