1. To send email you need to have a plugin which sets the "relaying" flag - currently the only one provided is the auth/flat_file plugin. And you need the deliver plugin enabled. I would also advise setting the port to 587 (the SMTP SUBMIT port).
2. You can read the read the body in the data_post hook (have a look at the data.signatures plugin for an example), and you can read the recipients in there from connection.transaction.rcpt_to (an array).
