Exchange 2000/outlook/email problem

Microsoft Exchange
We can not receive external email, local email seems fine. We are running Windows 2000 and Exchange 2000 (both up to date on patches, service packs, etc). We have three physical servers (DNS, Exchange and Print Server) We have and outside hosted domain which forward the the email to our system. It appears to me we continue to accumulate logs, and the databases grow in size. We can send and receive emails in the network (a T1 with a firewall) but now unable to receive outside emails, we can send however. Since we accumulate logs daily, the implication is that the mail comes in but not is accessible via Outlook (the queue is empty) There were no changes made to the system and was working fine. (about two years) The domain host was contacted, a non-technical person responded with it was us not them and we are unable to contact a technical person.

I am not sure if one or both of your servers have been blocked to outside mail. If you check on Microsoft’s site, and do a search on external mail blocked, it does come up with several remedies. The remedie for Exchange 2000 is:

Configuring an SMTP Server in Internet Information Services

If you want to use an SMTP server in Internet Information Services (IIS) to send outbound e-mail messages from Windows SharePoint Services, you must configure the SMTP server to allow anonymous access and to allow e-mail messages to be relayed. Note that the SMTP server you use must have Internet access to be able to send messages to external e-mail addresses.

Note The SMTP service for IIS is not installed by default. If you want to use the SMTP service that comes with IIS and have not installed the SMTP service, or you do not see the default SMTP virtual server in IIS, you must install the SMTP service manually. For more information about installing, configuring, and managing the SMTP service, see the Help system for Internet Information Services (IIS) Manager.

To complete this procedure, you must be logged on as a member of the Administrators group on the local computer, or you must be logged on using an account that is both a member of the SharePoint administrators group and that has been granted permissions to administer IIS.

Configure an SMTP server in IIS for use with Windows SharePoint Services

1. Click Start, point to All Programs, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.

2. Click the plus sign (+) next to the server name that contains the SMTP server you want to configure.

3. Right-click the SMTP virtual server you want to configure, and then click Properties.

4. On the Access tab, under Access control, click Authentication.

5. In the Authentication dialog box, under Select acceptable authentication methods for this resource, verify that Anonymous access is selected.

6. Click OK.

7. On the Access tab, under Relay restrictions, click Relay.

8. Under Select which computer may relay through this virtual server, select Only the list below.

9. Under Computers, click Add.

10. In the Computer dialog box, select Single computer, and then, in the IP address box, type the IP address for your front-end Web server or single server running Windows SharePoint Services.

11. Click OK to close the Computer dialog box.

12. Repeat steps 9 through 11 for any additional front-end Web servers in your server farm.

Note You do not need to add the IP addresses for the back-end database servers in your server farm.

13. Click OK to close the Relay Restrictions dialog box.

14. Click OK to close the Properties dialog box.

    I would first check with the support folks at your hosting domain, to see for sure where they are forwarding your mail to, check connectivity (make sure your server and their server can ping, tracert, etc.) This may include whether your local DNS service is operating correctly.

    Hi Baxter Some basic things you can check are.... 1. Are there any errors in your system and application event logs that mind indicate somethings going wrong? 2. Check all related Exchange servies are running, particularly Simple Mail Transport Protocol (SMTP) service 3. Check the queues in Exchange System Manager Cheers Griff

    Oh, also check disk space on your Exchange log/database disk(s)... Cheers Griff

    These probably aren't the problem, but it might be worth checking anyway: Make sure your firewall has an open port to allow inbound port 25 traffic to your server. Check your DNS records (A and MX records - to make sure you don't have a problem there. Make sure your Default Policy in Recipient Policies in Exchange System Manager lists your incoming domain name (ie: SMTP Rebuild your Recipient Update Services items in ESM. Make sure your "Default SMTP Virtual Server" Authentication allows for Anonymous access, and Connection doesn't have any limitations. Hope this helps, JP
