That is exactly what they should now be able to do.
By putting the user's IP address into /etc/postfix/pop-before-smtp.db, we
treat them as equivalent to a local user until the timeout expires.
Each time they pick up their mail, they will be authorized to relay from
that moment on for as long as you specify with the auth_duration parameter
Let me know how it works for you...
