/**
* Handles an incomming email
* Read the content of one email by using imap's functionality. If a ticket id is found inside the message_id or else in the subject line, then a reply will be added
* (if the email is not being sent from the authors email address it won't be added though and a warning will be sent to both parties). If no ticket id is found, then a new
* ticket will be created.
* @param $mbox a mailbox object
* @param $i the email's id in the mailbox (integer)
* @param $group the group object that owns the inbox.
* @return a string based on the found ticket i and timestamp (will be used to store a copy of the email locally)
