退信问题

wjw113

邮件系统最近恢复了一下，以前能发的一些地址，最近出现了些退信，大家帮我分析下。

mail.c-snd.com: 554 Service unavailable; Client host [mail.logistics.com] blocked using Barracuda Reputation; http://www.barracudanetworks.com/reputation/?r=1&ip=222.92.104.106)


(mail.messaging.microsoft.com: 550 Service unavailable; Client host [222.92.104.106] blocked using 88.blacklist.zap; Mail From IP Banned To request removal from this list please forward this message to delist@frontbridge.com)


奇怪的是222.92.104.106是我们公司网关的ip，我们公司邮件ip是222.92.104.99。
