I would like to do 2 things:
1. send emails over the Internet either using my ISP's smtp server or  
gmail's smtp
2. send messages to other machines on my network in a p2p fashion. My  
question I guess is would that require to host a mail server on at  
least one of the machines involved? If so then is postfix already  
setup for that?
