No idea. But it sounds to me like you want to use postfix to send mail
out, and fetchmail to bring in your email from local sites. You also
probably want one domain name attached to your outgoing mail, not a
return address which depends on which machine you happen to be on.

Remember however that a number of organisations refuse to accept mail
from DHCP (ie dynamic) IP addresses, so if your IP in those sites are
dynamic, you may find much of your mail bouncing.

Anyway, in postfix, the line myorigin is your friend. it is what is
tacked onto your return address.

Using postfix to receive mail is pretty useless for you since the world
has no idea where to deliver the mail to. You keep moving. So I assume
you have a machine with a permanant IP to which your mail is delivered.
Ie, that is the address which you use in myorigin.
