各位先进
小弟公司最近发现一些寄到gmail.com或者是透过google代管的server
被判为spam bulk sender./var/log/maillog内容如下
###################################
relay=ALT2.ASPMX.L.GOOGLE.COM[173.194.77.27]:25, delay=27710,
delays=27702/0/6.8/1.5, dsn=4.7.0, status=deferred

但事实上我们并没有发送大量邮件至gmail,有上国外网站google一一下
说有可能是因为mail forward 的问题
之前一直是正常的状况
之前也有向google发问后来一个星期后就又正常
但此次又同样发生了一个月以上
我们只好先将往gmail的信丢到另一台server(centos6+postfix2.6.6)寄送
请问各位有遇到这样的状况吗?可否协助解答一下
我们的server是centos5.5+ postfix 2.3.3 +mailscanner
国外网站说可以升级到postfix2.6.6作rate limited设定
此法是否可行???
谢谢
