更新后电子邮件通知失败

支持 安装

最近更新到最新版本后，邮件通知突然无法正常工作。

Sidekiq 出现以下错误：

obs::HandledExceptionWrapper: Wrapped OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=error: dh key too small

但我似乎找不到任何有用的相关信息。

我的配置如下，都是基本设置：

DISCOURSE_SMTP_ADDRESS: <smtp.domain.com>
DISCOURSE_SMTP_PORT: 587
DISCOURSE_SMTP_USER_NAME: <account@domain.com> 
DISCOURSE_SMTP_PASSWORD: '<password>'
DISCOURSE_SMTP_ENABLE_START_TLS: true           # （可选，默认为 true）

（出于隐私考虑已隐藏网址，但这些都是标准配置。）

There is a problem with your https certificates.

I guess my questions are…

A) Why is this problem something that didn’t exist before but does now, and how do i find out what that problem is. and

b) Why does that problem only affect smtp and not the site as a whole? My SSL certificates are valid until april 2020, and https is working fine on the site as a whole…

Is there any method to troubleshoot why discourse suddenly doesn’t like my ssl certificates for smtp?

The problem is this:

The SMTP you are using provides a DH key that is too small. Are you using your own SMTP server? If so, you are in good company. Rackspace had the same problem up until recently.

Email SSL Errors after Update to 2.4.0.beta4 - #11 by gerhard contains instructions on how to debug the issue and a temporary workaround. But you or your provider should really increase the size of the DH key.
