Send mail internal and external with two differents email servers

Microsoft Exchange
Microsoft Exchange 2003
Hi. I have Exchange Server 2003 installed on my local network but I don't have external email with this server. External emails are received on MS Outlook directly by the ISP (POP3). So, we have configured Outlook client with two email accounts (1. Internal Exchange, 2. ISP External Mail). If I try sending an email both for internal and external contacts I can't. Because I can send only external mail with my external account and internal mail with the internal account. There is some way to fix this problem before publish my Exchange Server? How can I receive an external email and reply both to internal and external users? (Because the external account receive the email and it try to reply, but this doesn?t know internal contacts x.500) Help please

a solution for your problem could be, to take a 3’rd Party product like GFI Mail Essentials ore Hexamail Exchange POP3 connector
to download your Users mail from your ISP and forward them to users mailbox.

    Hello, You could use a third party product to download mail from your ISP, but why not just configure your SMTP connector for Internet mail and do it yourself? This way your Outlook clients could send and receive local and Internet mail using one profile, you'd eliminate your ISP as a point of failure and have full control over your Exchange environment. Just a thought!

    As a happy medium between what you have currently and what petroleumman is suggesting, you could add an Internet mail connector to your server, forward all outbound SMTP traffic from that server to the server at your ISP, and have your ISP configure their end to route all of your company's Internet mail to your Exchange server. That way, you don't have the complexity of a completely self-contained messaging environment (you still have some benefit of the ISP "layer"), and your clients can still go to one server for all of their email.
