InfoPath Dev

Hello

I am working on a development. The process is I use MS access database to retrieve information onto a form in MS infopath ( Data connection set is MS access).The information which comes on the infopath form is limited . There are certain fields the user will have to fillout. This Infopath form will be emailed to the users. The users will fill up and send it back. Once sent back the information should automatically get updated in MS access or MS infopath . Is this possible. I could do the intial part sucessfully i.e pulling out information from MS access on a MS infopath, now stuck with the email part of MSinfopath...any ideas or suggestions?

Thanks
