XChange2000 Installation/Concept question

[MDoxsee]

To all,

I'm new to Exchange and need some guidance...

My company has been using MSMail for the longest time for internal messaging, and a paid external POP3 service from a Provider for external messaging.

Due to several limitations/problems (specifically the fact that each user has 2 addresses, one for internal and one for external), we have decided to move on and start using Exchange 2000 Enterprise for our messaging needs. (finally!

However, we will continue to use the external POP3 for the moment for external messaging (it is planned to eventually do it on our own, but I am not counting on it happening anytime soon...).

My question:
What is the best way to configure exchange to send/receive messages from an external SMTP/POP3 server? Also, do I need to configure DNS specifically for this (i.e. MX record) or can Exchange handle it on its own?
IMPORTANT: I want all the users to have ONE e-mail address only! Exchange should be able to figure out if it needs to stay "inside" or has to go "outside", but how do I configure this?

Some additional info:
Our domain: KLDLABS.LOCAL
Single Server Domain
Win2k Server SP4, AD
Exchange 2000 Enterprise
Basic DNS for AD

POP3 domain @ Provider: KLDLABS.COM

Any help or nudge in the right direction is greatly appreciated!

Thanks!
Michael

Internal addresses are not POP3, so there is no issue with that.
External messages can be retrieved using a POP3 add-on.
The one from

or

http://www.christensen-software.com/popconpro.htm

is a very nice one, handling multiple accounts if needed, and the Pro has anti-virus and Anti-spam options.
