Checking if email was read

Hello,

Would anybody happen to know if there is a way to use JavaMail to determine if the recipient has read the email that was sent to them? Here is what I mean:

1. An email is sent

2. A sender is informed that the receipient has read the email

Please, let me know what APIs I should use to make this work, if it is possible.

Thank you,

Victor.
