SMTP Mail Forwarding

I'm trying to set up SMTP on a Windows 2000 Server for incoming messages, but with some conditions that have proved to make the process a bit more complicated.

I'm trying to move our SMTP server from offsite to onsite and the conditions are that for ALL incoming messages, if it matches a validuser@ourdomain.com criteria, should be received in a single, central database. For example, adam@ourdomain.com goes to imail@ourdomain.com. andy@ourdomain.com goes to imail@ourdomain.com. sam@ourdomain.com goes to imail@ourdomaincom. blahblahblah@ourdomain.com is invalid so it gets bounced back. We are using Lotus Notes and have a Domino server up and running. The reason we do it this way is to because we have our emails manually routed and sorted by project databases for easy access and reference. We have hundreds of project databases which we will use as email addresses onto themselves, but we still accept email addressed to individual users.

What's the best way to go about this? Virtual Server seems to be limited in options, so I'm checking out MDaemon right now...but I can't see a way to forward all mails to one database. I'm wondering if MS 2000 Server can do this inherently or if there are any definitive 3rd party softwares out there?

Thanks.

 

It sounds like a DNS resolution problem.

Is your internal domain a ourdomain.com ?

May need to look at adding a forward lookup zone.
