differentiate between external and internal email addresses

I am trying to make a message rule that moves all emails from inside my company to a folder, and outside my company to a different folder.

How do you differentiate between external and internal email addresses in? This rule doesn't work:
Apply this rule after the message arrives
with  @mycompany.com     in the sender's address
move it to the    InternalEmails   folder

I am running Outlook 2000 SR-1.

Thanks for you help,

Hi josephfluckiger,
Have you tried this:
Create a group (or Distribution list) with the e-mail addresses of all your internal contacts.
Create a rule that moves all e-mails from people in the group (or distribution list) to a different folder.

Hope this helps!

Well There are about 1,200 people at my company, so that would be a little unwieldy. I was hoping to have an easier way.

The Exchange server appears to use a different format for internal email addresses. For example, here is the email address tab of the properties of my email address (I replaced by company name with "mycompany").

CCMAIL:Fluckiger, Joseph at ATL
X400:c=US;a= ;p=mycompany;o=ATL;s=Fluckiger;g=Joseph;i=S.;

So email address that never leave the company never get converted into their full SMTP format with @mycompany.com, they stay in the format mycompany/ATL/JSFLUCKI, and is why the filter on "@mycompany.com" does work.

Bartender's idea seems very smart. But I am not sure how many email address you can add in a distribution list.

I know there was a question in this area where a questioner said he was able to add only 535 in the distribution list ...

But I would assume you can create many distribution list and go from there .....

Well Bartender_1 is smarter than I thought he was :)

That worked like a champ! There was already a distribution list set up with everyone on it, so all I had to do was make a rule that says
Apply this rule after the message arrives
from ~Everyone
move it to the  InternalEmails folder

Thanks Bartender, and thanks sunray for helping me realize how smart Bartender's answer was. ;)
