推荐答案

您收到错误代码554： Access Denied Relay 。

You are getting an error code 554: Access Denied Relay.

可能是因为您的SMTP服务器无法将您的请求视为合法，并将其阻止为垃圾邮件。

It can be caused because your SMTP server doesn't recognise your petition as legit, and blocks it as if it were SPAM.

也许您的来自帐户与服务器预期域不匹配，或者您需要在SMTP连接中添加一些附加的身份验证参数（如果没有关于代码的更多信息，很难知道） 。

Perhaps your from account doesn't match the server expected domain, or you need add some aditional autentication parameters to your SMTP connection (hard to know without more information on your code).
