3.这个错误提示也是比较常见的:
65 5.7.1 unknown[59.36.99.230]: Client host rejected: Your message was rejected due to spam filtering based on the IP a
。
IP a 是一个怎样的IP地址?对方的防火墙设置了规则拒绝了我们的邮件吗?
4.在同一台机子上用同样的客户端(foxmail)公司的邮箱(name@sglog.com.cn)发邮件到hotmail是发送不了的,但用私人的163或126的邮箱就可以正常发送,错误提示是:无法将您的邮件投递至以下指定地址: zhanghuanmin08@hotmail.com : 550 OU-001 Mail rejected by Windows Live Hotmail for policy reasons. Reasons for rejection may be related to content wit。这是为什么呢?
