我刚才特地测试了一下，是成功的，最好能贴下日志。

你在中继那儿没有输入用户名和密码？
日志贴在下面，我有把mail地址更改过了。

我没有填，我是从一台测试服务器向正式服务器转发做的测试。

估计和我的外部企业邮局设置有关系，因为他们不允许中转。而你的可能没有这方面设置问题。

关于特定帐户转发帖子还没找到，如果有链接请贴下给我，谢谢！

因为我的正式邮服也是禁止中继并验证FROM的，所以理论上应该也是可行的，可能是不兼容问题。

纳入精华,继续讨论

发现我的MD在中继设置时，如果不输入用户名和密码点确定后再打开，就会变成图示情形，感觉是好像没有设置成功，不知道wxhsh的是不是这样。已经升级到MD最新版，也是一样。打电话去问MD的中国技术支持，还没回应。

刚试了一下，的确是BUG，用WA设置就正常了。
以下为我的截图：

测试了还是不行，打电话到MD上海，说如果外部邮局不开放中继是肯定不行。只有在中继设置用户名和密码才可以。不过发出去的mail头就是你设得这个邮箱头了

蛮奇怪的事，理论上中继发送成功不会改FROM的，对方应该看到的还是原发送者的地址，而不是中继地址，除非对方做了限制。
