I can help you set up sendmail with authorization.  It's quite simple.  
The idea is that your clients either check authentication required on 
their mail clients (ie. win Outlook) and point them at your mail server 
that's running sendmail as the MTA.  Linux boxes just point their mail 
clients at their own localhost sendmail which is told to use your mail 
server as their smart host.

sendmail on your mail server will then authenticate your clients using 
their user name and password.  They will also be able to relay through 
your mail server without problems.

I have to head out to work now but will send on the files this evening so 
you can see how it works.
