For some reason, I am not getting a mail from my discourse setup. I already tested my SMTP settings and they are working for other platforms Also tested it with Telnet.

See Troubleshooting email on a new Discourse install . A common problem is that Discourse is sending from an address that your server will not accept.

I am in a similar situation. Installed, website responds, registration e-mail never gets there. Tested sending e-mail from the discourse server, from inside the app container using the same configuration/credentials => works, test message sent and received correctly. Running doctor gives me: Sendin…

If you’re getting a read timeout it’s because the outgoing smtp port is blocked. You’ll need to get it unblocked or use another port.

I personally use the submission port on that server so that one certainly isn’t blocked. And - right - when using 587 the timeout error does not appear. Since I have no way to make the server’s configuration changes, should I understand that only SMTPS is supported?

Port 587 has explicit TLS (STARTTLS) and a mail server could be configured to accept submissions on that port without requiring TLS, so you could do unencrypted SMTP over that port. (The now sort-of-deprecated port 465 had implicit TLS and you had no choice there).

Right, the server is configured to work with explicit TLS on submission port (587). Now what does one need to do in Discourse configuration to make it work over 587 with TLS? Should/shouldn’t it work OOB?

There is DISCOURSE_SMTP_ENABLE_START_TLS which is default true.

邮件系统无法工作，尽管我用telnet和其他平台测试过

请参阅在新 Discourse 安装中排查电子邮件问题。一个常见的问题是，Discourse 发送的邮件地址不被您的服务器接受。
