<123@abc.com>: User and password not set, continuing without authentication
发布时间：2013-11-27 20:01:14
| 错误代码 | <123@abc.com>:
User and password not set, continuing without authentication.
123.125.50.213 does not like recipient.
Remote host said: 550 User not found: 123@qiye.163.com
Giving up on 123.125.50.213. |
| 形成原因 | 这种情况通常是由于：客户域名做了cname（不是mail.域名）,然后一些邮件系统在投递的时候，会把cname指向的域名替换原域名。 |
| 解决办法/流程 | abc.com做了cname指向qiye.163.com 。可能就是这样，123@abc.com变成了123@qiye.163.com 。
但是经查您的域名abc.com没有做cname指向qiye.163.com。
建议：
请与发信方服务器管理员联系，为何您的域名没有做cname ，却将您的域名解析为了qiye.163.com。 |
