Cannot send external email exchange server 2003

I have exchange server 2003 set up on server 2000. I am able to send mail and receive mail INTERNALLY. I am able to RECEIVE mail externally (from internet) I cannot SEND mail externally. I saw another post with a problem like this but no solution.

My messages go out with no error in outlook. When I look in the Exchange Manager and in the Queue..All my messages are queued waiting to go out. When I click on it says "An internal DNS error caused a failure to find the remote server." Nothing about DNS in the event review. I have set netgear router to forward port 25 to the ip address of exchange server. this is the smtp log file:

#Software: Microsoft Internet Information Services 5.0
#Version: 1.0
#Date: 2005-05-04 00:31:36
#Fields: time c-ip cs-method cs-uri-stem sc-status
00:31:36 xx.xx.196.50 HELO - 250
00:31:36 xx.xx.196.50 MAIL - 250
00:31:36 xx.xx.196.50 RCPT - 250
00:31:38 xx.xx.196.50  DATA - 250
00:31:38 xx.xx.196.50 QUIT - 240


btw, my DNS MX record is set to my ISP's IP and is working since im able to RECEIVE mail. I have tried putting an smtp connector to mail.optonline.net (my ISP) and still doesnt work.

Any help would be greatly appreciated. Thanks

i got it to work by changing the dns server in IP Properties to the exchange server's IP. It was the router b4.

Can anyone tell me how to access outlook webmail?

In IIS you should have the "Default Website" with a folder underneath it called "Exchange".  If so then it's a matter of http://exchangeserver2003.domain.com/exchange.

If it's not there then you might want to go back to the Exchange 2003 install disk to install this componant.

It's recomended that you set up IIS to use SSL to encrypt this though.

The link was this for me:
http://server-name.domain.com/exchange/

What I need is to be able access outlook web externally. I set the router to forward port 80 to my exchange server's IP (192.168.1.220).

So far this works internally but not externally. The public IP is http://ids.tzo.com/exchange. Can't get to it from the outside any ideas? I know Im doing something wrong here!

Looks like your firewalled.  Trying to ping gives timeout so I'm going to make a rash assumption that port 80 is still being blocked somewhere.

Double check your firewall/router and disable firewall for testing.
