日志正常却收不到邮件，请大家帮忙查看一下

huij

现在我这里有一个怪现象，有一客户发过来的邮件，从上海发过来就没有问题，我们可以正常收到，而从广州发过来，有收到日志，但邮件却收不到（日志附在下面，由于保密原因，我已经对收发人和IP更改过，请见谅）（他们的邮件服务器在广州）

以前我是对广州那个IP作为拒绝，但已经开通了，没再限制了，如果是拒绝的话，他们的邮件根本不可能发过来的，一连就拒绝，不会有接收邮件的日志的。
查了几天也没找到原因，我唯一的一个过滤规则只复制，不删除，而且是对关键字查找的。而黑名单没设，广州那个IP已经被我加入白名单，拒绝连接的IP和邮箱地址全没设。

头痛啊，那位兄弟姐弟帮忙分析一下有那种可能，谢谢了！

MD是否安裝了防病毒插件？操作系統的是否安裝了防病毒軟件？防病毒策略是什麼？
我想是因為收到了病毒郵件，然後被防毒軟件直接刪除了
