发给客户邮件时出现如下错误:
host xxx.mail.eo.outlook.com[xxx.xxx.163.247] said: 550
    5.7.1 Service unavailable; Client host [xxx.xxx.xxx..16] blocked using FBLW15;
    To request removal from this list please forward this message to
    delist@messaging.microsoft.com (in reply to RCPT TO command)
客户的邮件系统是Exchange,不知微软的过滤规则为何挡了邮件,为了让微软把我们移出黑名单,只能给他们发邮件申诉了,delist@messaging.microsoft.com,申诉邮件内容:
Please Helpme out to solve the belowisuue.
My Below IP Address are showing Blacklisted on below dns address IP Address:IP xxx.xxx.xxx.xxx . Please Help me and removemy ip from black list Thank you!

十分钟以后,会收到微软回复的邮件:
