求助：Failed mail delivery

今 天 早 上 我 发 出 30多 个 BUSINESS E-MAILS为 什 么 有 10多 个 Failed mail delivery？ ？ 下 面 是 返 回 的 E-MAIL。

A message you sent could not be delivered. The subject of your
message, reason for failure, and failed recipients are shown below.
Unknown host or recipient errors are often simply misaddressed. If
you tried to send a large attachment it might have been bigger than
the destination will accept. Other errors might indicate a temporary
problem with the mail delivery system itself.
