You need to allow relaying from whatever IP addresses your workstations (or
other email/relay servers) will be using.

in /etc/postfix/main.cf, you'll find the "mynetworks" and "relayhost" config
entries.  mynetworks defines which networks are trusted to relay mail. 
relayhost defines a "smarthost" that Postfix will forward all mail to (if it
isn't otherwise specified in /etc/postfix/transport table.

Of course, I prefer using Webmin (www.webmin.org) to do almost all my Postfix
configuration.

Lines I add that I CAN'T use webmin for:

# TLS stuff (might not work with this version)
smtp_use_tls = yes
smtp_tls_note_starttls_offer = yes
smtp_tls_key_file = /etc/ssl/private/devouredkey.pem
smtp_tls_cert_file = /etc/ssl/certs/devouredcert.pem
smtpd_tls_session_cache_database = sdbm:/etc/postfix/smtpd_scache

Also, if you ever have the host accepting main directly from the Internet,
look into the following lines (also in main.cf):

maps_rbl_domains = dialups.relays.osirusoft.com, bl.spamcop.net,
relays.ordb.org
smtpd_client_restrictions = reject_maps_rbl

This can be configured through Webmin, and allows blacklisting of open relays
(the source of 95% of Internet SPAM)
