I have an issue where I have a Win 2003 server running my MAS 500 ERP system and it is running a simple SMTP service to push out emails from our ERP system. I HAD a Windows 2003 server running Exchange 2003 and all worked just fine.
A few months ago, I installed a new Exchange 2010 server and pulled the Exchange 2003 server out of service. All of my email works fine, I have no problems, except with this server. I cannot get it to send out email using this SMTP service. This server gives me no error message either.
