无法从 spree 3、rails 4 发送电子邮件

Question

我很难使用 rails 应用程序配置 smtp。我过去做过很多次，没有狂欢，效果很好。但由于某种原因，我无法让我的 smtp 设置与 spree 一起发送电子邮件。

这是我的配置：

  config.assets.raise_runtime_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 465, # Doesn't work with 587 either 
    domain:               'gmail.com',
    user_name:            'email@gmail.com',
    password:             'emailPassword', 
    authentication:       :plain, # Tried :login too
    enable_starttls_auto: true
   }

我收到下面列出的几个错误Net::ReadTimeout: Net::ReadTimeout 和 Net::OpenTimeout: execution expired

下面是堆栈跟踪

我尝试设置 mandrill，认为 gmail 可能阻止了我的电子邮件，但也没有用。

注意：我希望能够使用 spree3 配置 SMTP，但我没有使用 spree_mail_settings gem。由于某些原因spree_mail_settings 对我不起作用。

任何帮助将不胜感激。

编辑 1：我知道我的 smtp 配置很好，但可能我必须设置一些 spree 相关的配置变量，让 spree 像以前版本的 spree 一样使用新配置。我浏览了文档并没有找到任何帮助。

提前致谢。

临时修复可以禁用 IPv6。将以下行添加到 /etc/sysctl.conf：

#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

然后从终端，您可以确认 IPv6（0 表示启用，1 表示禁用）：

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
