Converting attachments to PDF files automatically for a particular address

I am a new user of Exchange. For Mailboxes I would like that Receive and Send E-mail messages for a particular E-mail address should be converted to PDF file with possible attachment. (These PDF attachments will be saved in a file system structure such as: in —> mail domain of sender to sender to data to time to mail_obj.pdf out to mail domain of receiver to receiver to data to time to mail_obj.pdf). Any idea?
