Is there a way to configure Postfix to restrict outgoing e-mail per user so that he/she can ONLY send e-mails to one specific e-mail address?
For example: [email protected] where username is actually user login.

Your best bet here is a policy service such as postfwd or policyd; postfix does not natively have very good 1:1 rules.
It does look as if it is possible, the following documentation from the postfix website will give you a nudge in the right direction
