A couple of things need to be done. I setup postfix on a SuSE 8.1 box a few 
times to work with Outlook mail clients. There is a parameter line in your 
/etc/postfix/main.cf file that looks like this:

smtpd_sender_restrictions = hash:/etc/postfix/access

By default /etc/postfix/access looks to have a copy of the main page for the 
access file. Read through that and build an appropriate access file to allow 
user from your domain to send. 

Then make sure that Outlook is setup to have the from address match the domain 
that the server is serving. Then they should be able to send through that 
mail server. I'm sure somebody will explain why this solution will leave you 
vulnerable, but I don't claim to be a security expert.

Good Luck!
