Currently I am using a similar setup. My computer gets
a valid hostname from no-ip (malaquias.no-ip.org).
But I change the "From:" header line on the messages I
send (setting smtp_generic_maps in postfix config)
so that I get replies through my ISP.

Is it possible to use different authentications
for diferent users on my computers? There are
5 users, and each user has his own email account
in the ISP.

Is the following lines in main.cf enough to prevent that?
mynetworks_style = host
relay_domains =
