I would like to change the SMTP provider, but it doesn’t seem to work although I’m certain that the server can send emails. I have this in app.yml: DISCOURSE_SMTP_ADDRESS: <<SMTP SERVER>> DISCOURSE_SMTP_PORT: 465 DISCOURSE_SMTP_USER_NAME: <<USER>> DISCOURSE_SMTP_PASSWORD: <<PASSWORD>> Usi…

It’s likely that the outgoing port is being blocked by your hosting provider. If you’re using some service like mailgun (or most any other) then port 2525 should work. If it’s a mail server you run, then you can have it listen to another port (like 2525). Or (probably hardest) you can open a ticket…

Well, considering I can ./launcher enter app and then openssl connect to the mail server, login via SMTP and successfully sent an email from within the discourse container, I doubt that it is the port that doesn’t work…

I traced the code and it seems that EHLO wasn’t even reached. The SMTP server is connected but the SSL handshake seems to be missing, so the server quits and Discourse didn’t get any response, thus the error. So, I suspected that port 465 support seems to have a bug (it defaults to SSL, but I don’…

I think you’re right. And it turns out you’re not the first… when searching for DISCOURSE_SMTP_PORT 465 I found a whole pile of similar issues. Not able to send email Net::ReadTimeout - #18 by Stranik Email not working but i can access smtp server from container DigitalOcean + Siteground Email vi…

I’ve also seen quite a few ‘465 problem’ topics too. My email debugging for anything but the obvious is not great though so I have been quoting the troubleshooting guide: [图片] Troubleshoot email on a new Discourse install Email smtp port selection (Using 465?) The ability to be able to AUTH usin…

[图片] Richard - Communiteq: Well, if @schungx is able to confirm that DISCOURSE_SMTP_FORCE_TLS=true is indeed a solution, we can add that. I’ll try right away! EDIT: @RGJ I can confirm that DISCOURSE_SMTP_FORCE_TLS: true in app.yml successful solves the problem! :champagne: I suggest a bold…

嗯，如果 @schungx 能够确认 DISCOURSE_SMTP_FORCE_TLS=true 确实是一个解决方案，我们可以添加它。
