"send on behalf of" is different than "send as". Send as allows you to type the name of the account in the from field, and the email is sent "from" that account, not from you on behalf of the account. The "send as" permissions are found in the Security tab of the account. As for a dummy account that can send but no one can send to, in the Exchange General tab, configure the Delivery Restrictions so that it can only receive mail from itself. No one else will be able to send to it. We do something similar to this for the generic accounts we use for sending out notifications to users.

The sender (the Pres) doesn't want the "sent on behalf" to be in the From line - only his name.
