    My dentist used a service that claimed to provide a read-notification.

It was just an embedded web-bug in the email that I could choose to 
display or not ... if the client doesn't want to cooperate, you can't 
tell when the person read it.  All you could do is tell when a client 
downloaded it from dovecot...which doesn't say much for clients that are 
left on 24/7...
