我会在用户注册时发送确认邮件(和其他电子邮件)。问题是当我发送到不是 gmail 或 hotmail 或任何更大的电子邮件服务的地址时，它会在电子邮件标题中抛出一个错误。

我是否错误地设置了 header ，或者在我可以将电子邮件发送到自定义域之前是否需要设置配置？
最佳答案
似乎对于某些电子邮件服务，它需要您的域/子域的有效“接收”MX 记录(对于 Mailgun，它是 mg.mydomain.com)以验证发件人的身份.我添加了MX记录
10 mxa.mailgun.org
10 mxb.mailgun.org
mg.mydomain.com 似乎有效。
关于ruby-on-rails - 无法使用 Mailgun 将电子邮件发送到自定义域(非 Gmail/hotmail 电子邮件)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35547414/
