Get e-mail addresses from Gmail messages received
I teach a class on using Mathematica, and in the first "lab", the students enter their email address, and these are sent to a dummy email address I have set up just for this purpose (let's call it Math@gmail.com). So in this gmail account, I have many emails that are both To and From Math@gmail.com, the subject has some confirmation code in it (not important), and the body contains the actual email address of the student. Is there a way to extract these email addresses from the body of the messages, and add them to a contact list (Google+ Circle)? Or is there a better way to achieve my goal, which is automatically creating a list of emails for students in my class?
