I have remote users on SBS 2003 that pop in to get their mail...we had mail going through my isp account i.e a bellsouth.com. We have now switched isp and they do not offer relaying. How do i setup my exchange to allow authenticated users to relay mail. I have port 110 in my firewall going directly to my exchange box and im still getting "none of the authentication methods are supported by your server" on my client. I have the client setup to use the same username/password as incoming since its on the same exchange...and under exchange virtual smtp server relaying is allowed to authenticated users check box, HELP
