Question

我在heroku中部署了一个应用程序，邮件仅在开发中成功发送，但未在生产中发送。我使用的是mailgun。以下是错误结果：

和我的config / environments / production.rb代码

config.action_mailer.delivery_method = :smtp
    ActionMailer::Base.smtp_settings = 
   {

     :address              => 'mailgun.org',
     :port                 => ENV['MAILGUN_SMTP_PORT'],
     :domain               => ENV['MY_DOMAIN'],
     :user_name            => ENV['MAILGUN_SMTP_LOGIN'],
     :password             => ENV['MAILGUN_SMTP_PASSWORD'],
     :authentication       => 'plain'
   }

  config.action_mailer.default_url_options = { :host => 'https://myapp.herokuapp.com/' }
  config.action_mailer.asset_host = 'https://myapp.herokuapp.com/'
  config.action_controller.asset_host = 'https://myapp.herokuapp.com/'

Answer 1

好吧，我没注意到我只使用'mailgun.org'代替'smtp.mailgun.org'作为地址。我将地址值更改为ENV ['MAILGUN_SMTP_SERVER']，然后它在生产中正常工作。

Rails - 无法使用mailgun发送生产电子邮件
