Discourse Email não funciona após instalação nova (servidor SMTP Zoho)

Após uma instalação limpa do Discourse em um novo servidor Ramnode seguindo estas instruções, estou tentando configurar o e-mail para interagir corretamente com um cliente de e-mail Zoho. Até agora, não consegui enviar nenhum e-mail usando o Discourse. Já verifiquei esta página: https://meta.discourse.org/t/cannot-get-email-to-send-using-zoho-mail/45554/4.

Ao testar meu servidor SMTP usando o swaks, um e-mail é enviado corretamente:

swaks --to me@example.com --from do-not-reply@sfhepbfree-bayarea.org --server smtp.zoho.com --auth LOGIN --auth-user do-not-reply@sfhepbfree-bayarea.org -tls -p 587.

Isso me leva a crer que há um problema com o Discourse. Usando as seguintes configurações:

DISCOURSE_SMTP_ADDRESS: smtp.zoho.com DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_AUTHENTICATION: "login" DISCOURSE_SMTP_USER_NAME: do-not-reply@sfhepbfree-bayarea.org DISCOURSE_SMTP_PASSWORD: "..." DISCOURSE_SMTP_ENABLE_START_TLS: true # (opcional, padrão true)

Recebi o seguinte erro:

530 É necessário emitir um comando STARTTLS primeiro.

Quais configurações são possíveis para as variáveis DISCOURSE_SMTP_? Por que o e-mail funciona com o swaks, mas não através do Discourse?

I don’t have any ideas. You might run ./discourse-doctor and see if its mail debug tester sheds any light.

Zoho won’t work for bulk emails. It’s against their policies.

Use mailgun or something similar instead.

That error is from the ./discourse-doctor

Can you point to where in their policies they forbid bulk emails? They just seem to have a strict anti-spam policy…

Anyway, I don’t believe that to be the cause of the technical problem…

I just recommended a less painful option for You. If you absolutely gotta have zoho to send emails, try contacting their support as they are the ones who can help with the error code. The recommended email providers do work well for discourse and I don’t see anywhere in the documentation where discourse recommends zoho or google apps for business to send emails.

And did you rebuild after you made those settings?

Does the host name of your forum match what the mail server is configured for?

I did rebuild. And I decided to give elasticemail a try. Now, with elasticemail, I have the rather intriguing problem that email works when test emails are sent with ./discourse-doctor (they arrive in my inbox, receive a 10/10 score at mailtester, etc), but I am not receiving the activation emails when trying to register for the admin account. The logs only say:

However, the email is not being logged in elasticemail at all. Any ideas?

I think I’ve seen a problem before where if the first attempt at sending the registration email fails it’s hard to get Discourse to try again.

Try going to /login and doing forgot password.

Nice! That worked! Thanks so much!

That information should perhaps be added to the email troubleshooting page?

Well, I think it’s more of a bug/UX issue that I’ve reported here: Wizard will not send validation email more than once.

@gerhard, did you have a chance to take a look?
