exchange2000的问题!!!<br>
<br>
最近我用联通的IP到中国企业网申请了一个WWW.EARL*.COM,然后又用另外一个IP申请了MAIL.EARL*.COM<br>
<br>
现在我一台PC直接挂到INTERNET上,该PC没有和内网相连接,是MAIL.EARL*.COM这个IP.我把这台PC做成了AD,DNS设为MAIL.EARL*.COM.装上EXCHANGE2000做EMAIL服务器.安装好后建立了两个EMAIL帐号,123,567<br>
<br>
现在我用123@MAIL.EARL*.COM向567@MAIL.EARL*.COM相互发送邮件,在哪里都可以发送和接受(只要能上网的地方都可以)<br>
<br>
但是我用123(567)我的21CN上的MAIL发送邮件时,系统显示已发出,但是,21CN上的却收不到.而123(567)却收到系统的以下警告:<br>
<br>
This is an automatically generated Delivery Status Notification.<br>
<br>
Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server.<br>
<br>lzh523@21cn.com<br>
<br>
但是,我的21CN发送的邮件,123(567)确都能接受的到<br>
<br>
请高手大大们帮我解决一下,谢谢了<br><br>

刚才用WWW.DNSREPORT.COM检查了一下我的电脑,出现一下提示<br>
Getting MX record for mail.earlresort-hotel.com... There is no MX record for mail.earlresort-hotel.com! That's bad.<br>
Checking for an A record... Got it!<br>
<br>
Host Preference IP(s) [Country] mail.earlresort-hotel.com 0 61.242.108.21 [CN] --------------------------------------------------------------------------------<br>
<br>
<br>
Step 1: Try connecting to the following mailserver:<br>mail.earlresort-hotel.com - 61.242.108.21<br>
<br>
Step 2: If still unsuccessful, queue the E-mail for later delivery.<br>
<br>
<br>
Note: if you enter an entire E-mail address (such as postmaster@mail.earlresort-hotel.com), we will try to connect<br>
to each mailserver to ensure that they are live and accept mail to the mail.earlresort-hotel.com domain
