"getaddrinfo：提供节点名称或服务名称，或未知"用于 Mandrill 电子邮件注册

Question

我正在使用Mandrill API管理rails项目上的action_mailer。我正在遵循一个教程，做每件事都很好，而我本应该得到确认。相反，我这样做：

Devise::Mailer#confirmation_instructions: processed outbound mail in 26.2ms

主动支持（4.2.4）

知道我如何解决这个错误吗？

谢谢！

我认为这不是Mandrill的问题，而是DNS解析的问题。尝试此链接getaddrinfo:nodename或servname未提供，或未知

HTH、
