Hi I am having an exchange server 2000 running on windows 2k server terminal, and I followed the steps in the article in: to set up the server to send and receive external emails and it is sending but not receiving. I get this message when I try to send from outside: ******************************************************** Your message did not reach some or all of the intended recipients. Subject: RE: test Sent: 30/12/2004 10:00 AM The following recipient(s) could not be reached: Administrator on 30/12/2004 10:01 AM You do not have permission to send to this recipient. For assistance, contact your system administrator. < #5.7.1 smtp;550 5.7.1 Unable to relay for> on 30/12/2004 10:01 AM You do not have permission to send to this recipient. For assistance, contact your system administrator. < #5.7.1 smtp;550 5.7.1 Unable to relay for> ******************************************************** the MX entry is successful on the domain regstration company, I can ping it and telnet to port 25. The Exchange server uses the DNS IPs supplied by the domain registration company. The port forwarding on the Netgear router (FVS318 Prosafe VPN Firewall) is configured, and the internal DNS has a host entry mail pointing to the internal address of the mail server, any help is appreciated, thank you, Manal

When you attempt to send mail to an Exchange 2000 Server recipient or Exchange Server 2003 recipient, the message may not be delivered. The sender may receive a non-delivery report (NDR) from the system administrator similar to the following:
The following recipient(s) could not be reached: on 11/01/00 8:14 AM

The originator does not have permission to submit message
dns; failed 5.7.1 smtp;550
5.7.1 Unable to relay for

While there are several causes for this error, the most common one is that there may be no recipient policy for the expected domain in the Exchange 2000 organization or the Exchange 2003 organization.

Add a recipient policy for the expected domain. To do so:

1. In Exchange System Manager, expand the Recipients object, then expand the Recipient Policies object.

2. In the right-hand pane, right-click the Default Policy, and then click Properties. Click the E-Mail Addresses tab.

3. Click Add to add a new SMTP address.

4. In the SMTP Address Properties dialog box, in the Address field, enter
where is the domain that then sender is attempting to send to. Click Apply, and then click OK.

5. In the Default Policy Properties dialog box, click the E-Mail Address tab, and then click to select the check box next to the SMTP address that you just created.

6. Click Apply. Click OK when you receive the following notification:
The e-mail Addresses of type(s) [smtp] have been modified. Do you want to update all corresponding recipient e-mail addresses to match these new address(es)?

NOTES: If you would like to make the new SMTP address the default reply-to address for all users in your Exchange 2000 organization, click the new address, click Set as Primary, click Apply, and then click OK.

If you want to update these addresses immediately, force the Recipient Update Service to update your Exchange server and organization.

    Hi, If you've tried the above advice and assigned a recipient policy to the domain and still are getting your error, take a look at the Relay Restrictions tab (Exchange Systems Manager -> Administrative Groups -> Exchange Domain -> Servers -> Your Servername -> Protocols -> SMTP -> Virtual Server) right click your virtual server and choose Properties, click the Access tab and click the Relay button. Make sure you have the "Allow all computers which successfully authenticate to relay regardless of the list above." option checked. It is a good idea while your there to make sure you have the "Only the List Below" radio button checked under "Select Which Computers may Relay Through This Virtual Server" section and have your Exchange server's IP address listed and Access Granted displayed. This will lock your server down preventing it from being used as an open relay. This should resolve your problem. Good Luck!

    Thank you so much, the first solution was already there, and the second solution solved the receiving problem, now I can receive on this server, but I couldn't remember the change that I have done, and disabled the sending now :) it sounds funny, I think I just added in the configure button (in the smtp virtual server properties - delivery tab, clicking on advanced, then clicking on configure), external dns addresses as given to us by the domain registration company + out local dns ips, thanks you for your help,

    Good Morning, Under the 'Advanced Delivery' tab - Configure External DNS, you want to list ONLY addresses to your external DNS hosts (where your public MX records reside). Do Not include ip's which point to your AD DNS source. You want to keep AD DNS and public DNS seperate. Be sure to include the addresses for redundant servers as well. Your ISP or DNS host will provide you a list of the primary and all secondary servers. Also, make sure you have an entry listed in the 'Fully Qualified Domain Name' field as well. You can click the 'Check DNS' button to confirm that your entry is valid. Exchange 2000 or 2003 does not require a reboot after changes but should you experience a lag in your delivery time after making changes, it dosen't hurt to stop and start the SMTP service to force a refresh or even reboot the entire server. If you still have latency issues and feel you have configured your server correctly,compare the delivery time between internal mail and external (internet mail). If your problem is with the internet mail only, ping the external DNS servers and check your response times. If your getting time outs or delayed response, contact your DNS host as they may be having an issue. Good Luck!

    Hi petroleumman and all When I fist done the previous changes, it delayed the sending outside, but then it successfuly sent, but after a while it stopped sending at all, and return delivery failure messages to all domains I am trying to send to. As you said, I pinged the domain for the mail servers I am sending to, and they are reachable, I send my ISP dns servers, and they reply back, and I removed any local dns servers, and restarted the server, and the problem persists, Will you or anyone gove more ideas to trouble shoot this one, thank you very much for your help, Manal
