Microsoft exchange 2003 smtp connector

You cannot take DNS lightly. Start with the basics. A Host records map Server to IP address. The extra link that Exchange needs is — Server to email domain name.

The next consideration is where to configure these MX records? I stress email domain, because this maybe different from the name of your Active Directory domain. Your internal Outlook clients send all their email to your server, however some of those emails have external addresses.

This outgoing email needs a DNS server with root hints. In this second instance, the ISP takes responsibility for finding the correct server to deliver the email. Whereas, internet email relies on MX records to find the mail servers. This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.

Even in the "inbound" scenarios outlined above, the connector is being used to send the email to another server. SMTP connectors are not server specific. They are stored in the AD domain as part of the Exchange org. Therefore when you are moving to a new server or introducing additional servers you will not need to create additional connections, simply adjust the existing ones. It is now becoming quite common for some of the large ISPs such as AOL and many others to tighten the configuration of their email servers in an attempt to reduce the spam being sent.

This has caused problems for many operators of Exchange servers as email from their servers are being rejected as well. This server will pass AOL's tests and should work for any others that you are having problems with. Click the "Add" button under "Local Bridgeheads" and choose your Exchange server.

If you have more than one Exchange server enter that one as well. Don't enter any Front End servers you may have. Click on the "Address Space" tab. If you don't then you have turned yourself in to an open relay. Enter the external domain that the other server is responsible for. If this is a subdomain of your main domain then enter subdomain. Enable the option "Allow Messages to be relayed to these domains". Remember that if you want your server to relay for a different domain to a different server then you need to configure a different connector for each server.

If you want to load balance the connectors then you can set multiple connectors at a cost of 1. You need to enable it by hand. Right click on your organisation name right at the top of ESM and choose Properties. Click 'Ok'. Step Three Click on 'Outbound connections' on the delivery tab. This will show you what outgoing SMTP port number you are configured to use - if your ISP is blocking port 25 enter port but even if they do not block it at the moment we still recommend using port anyway!

Step Four In order to get mail to relay through our servers you will need to setup the 'Smart Host' setting on this screen. This is what tells Exchange to delivery all mail destined for the internet though our servers. Enter the SMTP server name we gave - for example: mail. Any mail that is currently in the queue might not take these new settings so you might need to send a new piece of mail to test it. After sending a test email you will want to check the outbound queue on Exchange to make sure that the mail did not get stuck in your outbound queue because of authentication errors.
