ruby - 发生 Net::SMTPFatalError，550 中继被拒绝

Question

我在生产环境中收到此错误消息。这是在用户创建期间出现的，并且在创建用户时，一封带有密码和其他详细信息的邮件会发送给用户

Net::SMTPFatalError occurred in users#create:

  550 Relaying denied 

对此有任何想法吗？

Answer 1

This worked for me:

The servers MIP (Mapped IP) address needs to be added to the mail router's relay list. It was not added and that was the reason it was rejecting. The receiver IP address was added and the mail was sent again.
