Some mail is trapped in our SMTP queues.

We are running Windows 2000, and Exchange 2000. We have offsite internet e-mail. E-Mail clients are running Outlook 2000, and we are able to send mail interoffice through the usual Exchange 2000 routing, as well as send internet e-mail through our offsite SMTP server. In delivery options in Outlook, Internet e-mail is set to be delivered first.  The problem is that occasionally mails sent to external users sometimes slip through to the exchange server rather that through the internet email service and then get stuck in the SMTP queues because it is not an internet email server.

I just found the "forward all unresolved mails to host:" in the SMTP virtual server properties and have put the ISP's DNS name in here but this has not made any difference.  Exchange just keeps trying to send the message.  

Has anyone got any advice on how I can sort this?

Cheers

Your ISP probably isn't going to allow you to relay mail off their server. Is there any reason you can't allow your mail server to send mail to the Internet?

We are a small division within the company and we use exchange 2000 as our mail system, the main business provides us with internet email.  We have asked in the past if we can setup our own internet email server but we are not as they own the full DNS domain name.  So its sort of an internal ISP.  I have checked and this mail server will accept outgoing messages from any source so I thought that forwarding would have worked on this box.  

Any suggestions how I can get sort this or alternative solutions?
The first thing I would do is telnet to port 25 of your "ISP" server from your Exchange server to make sure you have connectivity. If that test passes, then open System Manager, go into your routing group connectors and create a new SMTP connector. You can call this "Internet" and selct the "Forward all mail through this connector to the following smart host". Enter the IP address of your ISP server. Select your exchange server as the bridgehead. On the Address Sapce tab, add SMTP - leave the email domain as *.

You are a star!  I had looked at this section before but didn't realise it was so straight forward all the documents, manuals, course notes I had looked at to fix this problem talked about vonfiguring additional virtual servers with virtual ip addresses, got what a nightmare, anyway thanks again another weight of my shoulders.
