我在论坛上看到，可以将 `DISCOURSE_SMTP_AUTHENTICATION` 设置为 `none`，这样 smtp 就不会提供用户名和密码。
```plaintext
DISCOURSE_SMTP_AUTHENTICATION: none
```
但是当我将其设置为 none 并尝试 `discourse-doctor` 时，我收到：
```plaintext
======================================== ERROR ========================================
UNEXPECTED ERROR
Invalid authentication method. Must be plain, login, or cram_md5.
====================================== SOLUTION =======================================
This is not a common error. No recommended solution exists!
Please report the exact error message above to https://meta.discourse.org/
(And a solution, if you find one!)
```
当我尝试登录时，我收到：

销毁并重建也没有帮助。
我在 Discourse 之外测试了我的邮件发送器，它可以正常工作。我使用的是 [bokysan/docker-postfix](https://github.com/bokysan/docker-postfix)，它不需要登录，我对它很满意。
我知道另一个相关的帖子，但 `none` 选项在那里似乎是一个有效的选项：

I’m trying to deploy Discourse inside an organization with a private email server which allows to send email from specific IPs internally but requires the applications to disable authentication when talking to it.

我已经通过注释掉 `containers/app.yml` 中的以下行来修复它
```plaintext
#DISCOURSE_SMTP_USER_NAME: user@example.com
#DISCOURSE_SMTP_PASSWORD: pa$$word
```
