Send & Receive of e-mail on Exchange

By AliveinMI ·
I am deploying Exchange Server 5.5, SP3 on a NT 4.0 Server, SP5.

The only way I could get the server to send and receive e-mail was to direct the mail towards my ISP's mail server. I have set up Exchange 5.0 at a different company and was able to send e-mail without sending via a mail server. I don't know if the problem is at my end or at the ISP. The DNS addresses ...etc are correct. I am able to receive e-mail that is directed to my router (Netopia R-3100U). The problem lies with getting the e-mail to go out without directing it to the mail server.

I am assuming that I have a incorrect setting or missing something on the Exchange server setup. Thank you in advance for any suggestions.

Send & Receive of e-mail on Exchange

Why would you want to install an Exchange server, only to have the clients bypass it?

Let's start with the differences between what you are trying to do now, and what you did at the other company.

You sent mail without using a mail server before, which means you probably had configured your email client to go through your isp. (You can still do this by configuring the client machines with Internet Email, even if you have an Exchange server. But you get more benefits from routing mail through your Exchange server.)

Now you have a mail server, and the differences are that you now have clients that will connect only to the mail server, and the mail server will be the machine connecting to your ISP.

To connect your mail server, you need to have the correct DNS settings, of course. Since it doesn't sound like you are running your own DNS server, you also need to have your ISP put in an MX record for your mail server in their DNS database. If you've done all that, then you just need to configure your Internet Mail connector and that's pretty much it.

According to my ISP the MX records are correct (we are receiving e-mail into the Exchange system). The problem is with sending e-mail from inside the company to the internet. The only way I got it to work was to give it a destination server tosend it to.

1) check TCP/IP settings on the server (TCP/IP -- Advanced -- DNS tab). It should point to DNS server of your ISP (or, any other working Internet DNS server)

2)try to ping a known FQDN like:
ping www.techrepublic.com (

in case you are sure 1)is OK but 2) does not work -- I can only imagine that your router does not pass DNS requests. Check packet filtering on your router. I believe it should allow trafic to/from port 53.

when pinging it may not answer (timed out) but it should RESOLVE FQDN to IP address !!!

Just a thought- is the IMS set up to reroute incoming SMTP mail? (radio button on the "routing" tab in IMS properties) If not you won't be able to relay mail out.

This is set correctly. Thanks for the input.

If you can receive e-mail, then your MX record is correct in the DNS.

Exchange 5.5 sends mail out through Connectors. The nice thing is that you can use the Internet Mail Connector to just blast it out into the 'Net, and the DNS figures out where to send it from there. Look in the Connectors container for an Internet Mail Connector.

If you don't have it, you have to Add New .. Other .. Internet Mail Connector. That will start a wizard which will set it up for you.

If you do have an Internet Mail Connector then you should check its Properties for any settings which might be incompatible with your ISP.

Good fortune,
Don
