Yahoo 电子邮件向 Exchange 邮箱发送延迟过高或无法送达

来自 Yahoo 邮件的带有附件的电子邮件无法送达我们的 Exchange 邮箱，或者接收延迟太久。附件越大，送达越晚。带有 10MB 附件的电子邮件根本无法送达，并且 Yahoo 邮箱中出现“失败通知”消息。接收连接器的最大大小设置为 15MB，从 gmail 发送相同的电子邮件成功送达我们的邮箱。分析已送达的 Yahoo 邮件的标题显示内部 Yahoo 服务器之间发生延迟：

注意“日期”标头，从 sonic.gate.mail.ne1.yahoo.com 到 sonic301.consmr.mail.bf2.yahoo.com 接收电子邮件的延迟，其中“已接收”标头中有 HTTP，延迟时间将近 12 分钟。显然，从 yahoo 向 gmail 发送电子邮件不会遇到此类问题，但其中使用了不同的内部 yahoo 服务器。

更新： 以下是返回到Yahoo邮箱的“失败通知”邮件：

答案1

该问题与 Yahoo 内部服务器有关，这里。也许他们对服务器进行了一些更改，因为现在只有带有附件的电子邮件会遇到此类问题，而不是全部。
