Update email records for lead from Unibox

We frequently get auto-replies saying "our company/ website/ email address changed, please contact at abc@xyz.com". It would be great to grab that information from the Unibox and enroll the new email address in the same campaign (possibly with adding some custom text "hey, John mentioned I should contact you about this"). This would also work great for OOO notifications (please contact clara@xxx.com) etc.
