I suggest that you take out an exchange manual or check exchange specific mailing lists.  Here are some links to get you started.  I do agree that if OTRS is the only thing needing POP3 access that you “secure” it similar to the way Dave explained in the first reply.

Subject: [otrs] OTRS on Windows SBS System

Hi All,
 
I have a Windows SBS2003 server running Exchange 2003, but not in POP3 mode. All emails come into that machine as the primary Mail Exchanger.
 
I have OTRS running on a second Windows Server 2003r2 Standard system, and want to get the incoming support emails from the SBS box. All I can see is POP3 settings, but they are not working, presumably because I am not running POP on the main email server.
 
Can someone assist me in making the correct setting changes to enable email reception? Sending is working fine.
 
Thanks
 
Mike Hayward
