Of course you could all just RTFM:
http://www.postfix.org/BASIC_CONFIGURATION_README.html#relayhost
"What delivery method: direct or indirect
By default, Postfix tries to deliver mail directly to the Internet.
Depending on your local conditions this may not be possible or
desirable. For example, your system may be turned off outside office
hours, it may be behind a firewall, or it may be connected via a
provider who does not allow direct mail to the Internet. In those cases
you need to configure Postfix to deliver mail indirectly via a relay
host.
Examples (specify only one of the following):
/etc/postfix/main.cf:
relayhost = (default: direct delivery to Internet)
relayhost = $mydomain (deliver via local mailhub)
relayhost = [mail.$mydomain] (deliver via local mailhub)
relayhost = [mail.isp.tld] (deliver via provider mailhub)
The form enclosed with [] eliminates DNS MX lookups. Don't worry if you
don't know what that means. Just be sure to specify the [] around the
mailhub hostname that your ISP gave to you, otherwise mail may be
mis-delivered. "
Then postfix will relay all mail through your ISP, just like any old
mail client that is set to your ISP's smtp server.
