relayhost is a good solution.  it can, however, be a problem if you 
connect through different ISPs.  because then, your default relayhost
setting won't necessarily work with all those ISPs (it *can*, if you
have POP3 auth before SMTP, or if you have some sort of authenticated
SMTP, but for generic unauthenticated SMTP, it's going to work with
one ISP, and fail with all the others.

SMTP forwarding over ssh is one way around this.  i did that when i was
travelling overseas a while ago.  when i'd go online, /etc/ppp/ip-up.local
would automatically setup the ssh forwarding of SMTP to my server in
the philippines, and then i'd just send to local SMTP (which would be
forwarded over ssh to the SMTP server overseas).

if you don't want to do that (e.g., if you don't have an SMTP and ssh
server that you can control enough to do this)  then you can modify the
relayhost in /etc/postfix/main.cf everytime you dialup, to the correct 
one (or just have a different main.cf for each ISP you connect to,
with the correct relayhost setting and copy that main.cf.<isp> file
to /etc/postfix/main.cf and kick postfix from /etc/ppp/ip-up.local).

there are other ways around that too.  i used to have a setup that
would run a sed replacement on config files depending on which
ISP i was connected to, so that things would work (DNS, squid proxy
forwarding, SMTP, etc).
