When you connect to your Exchange server using Outlook, you are using
Microsoft's specific protocols to communicate. When you connect to Exchange
from CF using CFMAIL, you're using SMTP. Your Exchange server needs to be
configured to allow SMTP relaying from your CF server. Google "Exchange SMTP
relay" to find out how to do this.
