(10)单封邮件收件人数超过限制
错误原因: 单封邮件有过多收件人
可能出现的关键字: Too many、less than xx
解决方法: 邮件系统会对每一个邮件投递者每次连接时候的同一封邮件的多投用户数量,因此当用户使用群发时候就会出现对方拒收或者错误的信息返回如"Too many recipients"信息。因此用户请再每一封邮件投递时候,尽量使得每次的接收用户数量控制在20~30人左右,如果接收量比较多的情况,可以分开多几次发送。
Winmail Server 退信实例:sorry, too many recipients
其他系统退信实例:
<*****@email.com>: host …… said: 553 Too many recipients in the mail, should less than xx
(11)反垃圾邮件列表
错误原因: 发信服务器地址被加入到某些反垃圾邮件组织的黑名单中,导致拒收
