I am using system.net.mail in vb.net 2005 in an application we have.  I am able to send mail when I am logged into the network as domain admin and logged into the application as any email user, but users are not able to send when logged into the network as themselves.  
In active directory I made the necessary users members of Exchange Organization Administrators and now they have permission to send mail.
I would rather make them members of a more secure group that still grants the permissions necessary.  Any suggestions?
Thanks.
