| 错误代码 | Host abc.com(208.245.163.148) MAIL FROM said 453 Blocked by NSBL |
| 形成原因 | 表示发信IP或发信域被某个RBL加黑 |
| 解决办法/流程 | MAIL FROM said 453 Blocked by NSBL，退信表示发信IP或发信域被某个RBL加黑。我们使用网易企业邮箱测试发送邮件，是可以成功发送的，表示对方没有拒绝网易服务器。有可能是邮件内容触及收信服务器策略。
请测试发送内容较简单的邮件：如果邮件成功到达，则可能是由于邮件内容而拒收邮件；如果邮件投递失败，则可能是由于使用的IP而拒收邮件，可再测试在其他IP上发送。认为是收信服务器误判，可建议收件人向其服务器管理员投诉，谢谢！ |
