ruby-on-rails - Rails 3:OpenSSL::SSL::SSLError:主机名与服务器证书不匹配

Question

当尝试通过控制台发送电子邮件时，我收到此错误:

OpenSSL::SSL::SSLError: hostname was not match with the server certificate

问题是我真的不太了解证书等，或者真的不太了解如何开始解决这个问题，我尝试使用 openssl 进行一些调查，这是返回的证书.

我不知道是否是服务器上运行的 Postfix 或我的 Rails 应用程序的问题，非常感谢任何帮助或线索。

Answer 1

比接受的答案更好的解决方案(就安全性而言)是:

ActionMailer::Base.smtp_settings = {
  :address              => "mail.foo.com",
  :port                 => 587,
  :domain               => "foo.com",
  :user_name            => "addy@foo.com",
  :password             => "foofoo",
  :authentication       => "plain",
  :enable_starttls_auto => true,
  :openssl_verify_mode  => 'none'
}

这样您仍将使用加密，但证书验证将被禁用(并且您不会收到任何错误)。
