邮件服务器被当跳板，怎么办？

我们有一台邮件服务器 是Sun Java(tm) System Messaging Server 6的

运行在solaris上


从日志中发现有人使用我们的邮件服务器转发邮件，导致我们自己发送邮件的速度很慢。


找了好久也不知道如何关闭open relay






现在我只想确认是否真的开启了open relay(匿名转发)





有测试结果了，我就奇怪了，我也没开open relay，为什么有人用我们邮件服务器转发呢


Relay Tester:
Testing email.szns.gov.cn...


Connecting to email.szns.gov.cn ...
