Postfix is /not/ open relay by default, so you must have been doing
something wrong to make it abusable.
Maybe you added a domain in access.db with an OK, or you left out
'reject_unauth_destination' from 'smtpd_recipient_restrictions', I
can't tell without more info.
Post the output from 'postconf -n', it's likely that gives more
clues.
