现在我有一问题 我在服务器上装了IMAIL 8.15所有服务启动 能收到外网发的信件（如163发信 是可以收到的）。但是向外发信成功 外网就是收不到信件。还有一个问题就是我们另外一台服务器上装的IMAIL 上面的邮局是可以收到这台服务器发送的邮件 我看了所有服务都没有问题 防和墙关闭什么安全都没设置 还是一样的效果。重新安装一次IMAIL 是可以向外发信也是能收到的，但是过一天就又不行了，
日志如下：

确实是很奇怪的日志，需要远程看下具体情况。

网上找的:

原因：是网络出现故障。
解决方法：先把Imail服务全部关掉。你把邮件服务器中所有的邮件帐号禁止掉。把Imail的目录中的Spool目录名字改掉，另外创建一个空的Spool目录。然后开启Imail服务。

应该是他的防毒软件把imail的对外连接当作木马连接给屏蔽了
