企业邮箱使用smtpClient老提示错误

我使用的是万网的免费企业邮箱，在进行测试的时候，用到c#里面的smtpClient进行邮件放送的时候，老是提示：不允许使用邮箱名称。服务器响应为: authentication is required smtp 服务器我用呢：smtp.mxhichina.com 端口25

qq邮箱发信给阿里云企业邮箱时提示邮箱地址不存在或格式错误！求解

我在万网注册的免费版阿里云企业邮箱，经过服务器解析一系列忙活，企业邮箱能发信，而且能收到内域来信，但是客户用外域邮箱，比如qq邮箱，发信给我的企业邮箱，则提示“ 邮箱地址不存在或格式错误”！求解！

企业邮箱使用smtpClient老提示错误怎么办

提示为：不允许使用邮箱名称。服务器响应为: authentication is required 服务器我用呢：smtp.mxhichina.com 端口25 smtp.aliyun.com我也试了也不行
