邮件弹回分两种，硬弹回和软弹回。
硬弹回主要指邮件发送对象的地址有误。软弹回原因较复杂，如邮件已满、服务器暂时连不上。
如上实例说的是Yahoo对我发送的邮件，以往没有问题，但上一次Yahoo收到邮件弹回。
什么原因？可能是邮箱失效了，可能是服务器屏蔽Yahoo邮件发送未包装弹回。。。实际情况是，我的邮箱一切正常，今天重新收到Yahoo邮件。
Yahoo为此的处理，
- 数据库中此邮箱地址旁加一栏标签，说明发生邮件弹回；
- 对此邮箱再次发送，请求重新激活，并将激活动作记录到数据库中；
- 对于未响应激活请求的邮箱不再发送邮件，除非以后重新被激活。
看似很小问题，Yahoo做得精道。
接促许多专业邮件发送服务商，其中不乏世界知名品牌公司。在此细微处无一做好。
邮件发送服务商们，看到了吗？希望对你们有帮助。
