I just saw this domain value on Email Settings page, I didn’t see it during installation. Where to set this domain value? <a class="lightbox" href="https://global.discourse-cdn.com/meta/original/4X/b/e/e/bee67a32b8e63ba3f18494af440d4a32eb2cf7b9.png" data-download-href="/uploads/short-url/reMvUTzmVHQCGXg3bxrOAx9raNr.png?dl=1" title="This image shows an email settings page with options for configuring server settings, including the domain "discourse.example.com," for emails sent to members.

It’s probably set in your container configuration file, the default contents in the template are: DISCOURSE_SMTP_ADDRESS: smtp.example.com #DISCOURSE_SMTP_PORT: 587 DISCOURSE_SMTP_USER_NAME: user@example.com DISCOURSE_SMTP_PASSWORD: pa$$word #DISCOURSE_SMTP_ENABLE_START_TLS: true …

since no one is jumping in I think it is in app.yml ??? I think there is a command line way to set your mail setting as well. ah… look here [圖片] Troubleshoot email on a new Discourse install Self-Hosting You just installed Discourse via the install guide , but…

[圖片] supermathie: The default value is blank: As far as I can remember, I didn’t see and/or didn’t enter any such value so installation process must be filling this from somewhere? I just re-installed and still didn’t see any option to fill this field.

[圖片] supermathie: It’s probably set in your container configuration file, the default contents in the template are: Finally we found it Yay! :slight_smile: So how do we change it?

[圖片] sallypf: So how do we change it? Edit the file and change it.

from link in post 2 above If you change just SMTP settings, you can do just this to apply them without doing a full rebuild: cd /var/discourse ./launcher destroy app ./launcher start app

既然没有人介入，我认为它在 app.yml 中？？？
我认为也有命令行设置邮件的方法。
