不能发送邮件（不知是发邮件有问题还是收邮件问题）

xuefang2402

我在自己的虚拟机上搭建了一个系统模拟环境，使用的是IIS5.0 ， win2k server，装好MDaemon之后，建立了几个用户，然后在另一个虚拟系统中登录，登录进去没问题，可是发送邮件后却收不到，弄了半天也不知什么原因，希望能有高手帮忙解决，谢谢！

说清楚一点，也许会让更多人明白

谢谢管理员的回复。
后来我想了想，可能是DNS的问题，但我配置了一下DNS后，依然不行，提示错误：
error sending message! 550 5.7.1 unable relay for flp@mail.cn

在服务器的日志里记录的是如下：

為什麼會有mypc Microsoft ESMTP MAIL Service？
檢查IIS中的SMTP是否是開啟的。
