Can send to certain addresses but not others

I am using Outlook 2007.
Can't figure out why I can send some emails within my company... but anything to another email address will not work.

This is my "Undeliverable" email return message from "System Administrator"

Your message did not reach some or all of the intended recipients.

Subject: Test

Sent: 7/14/2011 11:31 AM

The following recipient(s) cannot be reached:

'test@email.com' on 7/14/2011 11:31 AM
550 #5.1.0 Address rejected test@email.com

***I have tried selecting "My outgoing server (SMTP) requires authentication"...

Please help!!!

If this happens with all external emails then probably it is restricted by your network administrator.
