sendmail退信 (reason: 553 sorry, invalid mailhost)

diocorns

新近架设一台sendmail，出现一个问题：所有发给浙江大学的信（zjuem.zju.edu.cn）的信被退信，而发给其他mailserver的信没有问题

退信内容：
----- The following addresses had permanent fatal errors -----
<name@zjuem.zju.edu.cn>;
    (reason: 553 sorry, invalid mailhost. (#5.3.3))

   ----- Transcript of session follows -----
... while talking to spam.zju.edu.cn.:
>;>;>; MAIL From:<myname@mydomain.com>;
<<< 553 sorry, invalid mailhost. (#5.3.3)
501 5.6.0 Data format error

对 sendmail 不太熟悉，在qmail中，这种情况是 rcpthosts 文件里 没有这个域，你看看 sendmail 里面是否有这种文件

flash520

我安装的Qmail也有这种用smtp发送不了邮件的情况，我查看了/var/qmail/control/rcpthosts文件，里面有使用域名，为什么还是发送不了呢。

收是正常的，在igenus 下收发都正常

我这里是horde下面也出现不能给浙江大学mail服务器发信的情况，看来是sendmail里面的问题
各位大大畅所欲言啊

思一克

mydomain.com不可以，
是对方ANTI-SPAM阻挡了？

换为qmail后，原因不再存在，只能说sendmail我搭建的不好，qmail年中用到现在，重启过2次系统，最长运行将近4个月，情况稳定良好
