Track the Mail read, unread status from sender Inbox

Hi All,

My requirement is to track the mail is read by someone or not in sender Inbox. For ex- I send the mail to sender. Now I want to track the status(read/Unread) of my mail. Is it read by someone or not.

Pytracking module is capable to do this. Can someone plz suggest me the some examples or helpful link of Pytracking.
