请教，exchange通过ISA发布出去，只能收外网邮件，不能发，总是隔了好长时间被退回来。<br>
有谁遇到过吗？请指教，急呀，555555555555<br>
而且在exchange smtp队列里有大量的要发出去的邮件都是：retry, 邮件服务器DNS是外网的也可以解析外网邮件地址呀，邮件服务器也可以上网。<br>
大家帮我分析一下退回来的信息，发表一下意见问题出在那拉<br>

应该不是dns的问题呀，我用nslookup可以解析到yahoo的MX地址<br>
> sssbj.net<br>
Server: xxx.xxx.xxx<br>
Address: 192.168.1.6<br>
<br>
Non-authoritative answer:<br>
sssbj.net MX preference = 10, mail exchanger<br>
sssbj.net MX preference = 4, mail exchanger<br>
<br>
sssbj.net nameserver = dns1.hichina.com<br>
sssbj.net nameserver = dns2.hichina.com<br>
mail.sssbj.net internet address = 218.30.103.165<br>
dns1.hichina.com internet address = 218.30.<br>
dns2.hichina.com internet address = 202.106<br>

我的Exchange就是用ISA发布出去的，很正常。<br>
发邮件要有三个条件：<br>
1、你的服务器网关指向ISA内网ip地址。<br>
2、你的电脑能上网，就DNS正常。<br>
3、你的ISA服务器出去时pop3、smtp端口要开放，而且还不需要限制用户及IP地址，可以这样测试在exchange server上，telnet xxx.xxx.xxx.xxx 25，是一个网外的邮件服务器。
