为此挣扎了一段时间。 已经到处search，阅读每一个post/线程，我可以find并有一个线程开始微软的“答案”网站，但答复是如此缓慢。
我正在运行Plesk w PostFix和电子邮件正在成功发送到Microsoft服务器，但电子邮件永远不会到达收件箱（或垃圾邮件文件夹，或其他任何地方），但也不会反弹。 他们只是悄无声息地丢在某个地方。
我有SPF，DomainKeys和DomainKey签名正常工作：

电子邮件function正常否则 – 服务器每天会处理数百个（如果不是数千个）电子邮件，并且没有任何问题发送到/从任何其他服务。
我不知道下一步要检查/尝试什么，而且会喜欢一些帮助。
在Exchange服务器上运行get-messagetracking。 或者让系统pipe理员去做，如果不行的话。 如果是微软，请与他们打开一张票。
SMTP 250是一个成功的代码，所以从他们的angular度来看，他们的系统中的某些东西正在丢掉球。 从技术的angular度来看，没有什么可以做的，如果你不pipe理给你的sendmail 250的系统。
按照这里的步骤使其工作。
