Email addon - how to bring an email together with a client or contact?

I'm using the mailaddon. When i send a Mail through the addon or i receive a mail through the addon, i can't bring theese mals together with the client or contact in recruit. I need a mailhistory for the clients and contacts.
Is it possible to exchange mails from the addon to recruit ond vice versa?
