Outlook Exchange and pop3 relay problem

[Azazel]

I have a problem, I have an exchange server working internaly through
outlook and pop3 accounts working directly to the outside pop3 server
from outlook. When I try sending mail to multiple users of which some
are internal and some external the program sends all the messages
through the external pop3 account. Even though I have the exchange
server set as my default account, when I send a message to an exchange
user, forwarded from a recieved message through pop3 it also sends the
message through pop3 overriding the default settings. My question is:

Is there any way of setting the program or the exchange server to relay
the messages depending on the recipent ??

OH an I forgot, I'm running a Win 2000 Exchange Server, but I have
Office 2003 installed.

Isn't your Exchange server connected to the outside world?

The server is connected to the outside world, but we still have the pop3
settings in outlook set, the server dosn't relay incoming messages, they
are inported directly from the pop3 server.

Next to the Send button you have an Accounts button. Set it to use the
Exchange server instead of the POP3 server. Make the default SMTP address of
your Active Directory account the address you have of your POP3 account so
people can reply to the message.

If only the solution was that simple, but it isn't :-(
I've tried all different kinds of tricks, and nothing helps, the default
acc is set, the smtp is set to the exchange server, I contacted my ISP
to see if it was their problem, but it wasn't . This is the message I get:

The following recipient(s) could not be reached:

(e-mail address removed) on 6/1/2004 11:18 AM
The format of the e-mail address is incorrect. Check the
address, look up the recipient in the Address Book, or contact the
recipient directly to find out the correct address.
<exchange.server.com #5.1.3>

Any other suggestions ??
