and also, whenever i try to send a message to my test_list, i get a bounce 
with no header:

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

       Subject:  test message
       Sent:     8/21/2003 3:56 PM

The following recipient(s) could not be reached:

       'test_list at lists.skimoguls.com' on 8/21/2003 3:56 PM
             Unable to deliver the message due to a communications failure
         The MTS-ID of the original message is: c=US;a= ;p=Moguls Ski ? 
Sno;l=MSSTNT1-030821215600Z-45543
             MSEXCH:IMS:Moguls Ski & Snowboard Tours:MOGULS:MSSTPDC 3550 
(000B09AA) 550 5.0.0 Access denied

seems like it's denying relaying, but i don't know where i set it to relay 
off the exchange server.

maybe i should just switch and try my hand at postfix.
