postfix is not sending mail external

Hello I have instaled suse8 with postfix 1.1.12

I'm haveing trouble with sending mail remote to the internet.
I have configured my Outlook Express to send mail throught postfix.
When the account is a local account there is no problem it is delivered but
when it some other domain it gives an erro
" The message could not be sent because one of the recipients was rejected
by the server. The rejected e-mail address was 'hlopes@csapo.pt'. Subject
'teste', Account: 'Helder J Lopes', Server: '192.1.1.221', Protocol: SMTP,
Server Response: '554 <hlopes@sapo.pt>: Recipient address rejected: Relay
access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number:
0x800CCC79"

The configuration that I got are
inet_interfaces = all

mynetworks = 192.1.1.0/28, 127.0.0.0/8

relayhost = mail.telepac.pt

readme_directory = /usr/share/doc/packages/postfix/README_FILES

mail_spool_directory = /var/mail

mail_name = Postfix on SuSE Linux 8.0 (i386)

sender_canonical_maps = hash:/etc/postfix/sender_canonical

canonical_maps = hash:/etc/postfix/canonical

virtual_maps = hash:/etc/postfix/virtual

relocated_maps = hash:/etc/postfix/relocated

smtpd_sender_restrictions = hash:/etc/postfix/access

transport_maps = hash:/etc/postfix/transport

masquerade_exceptions = root

masquerade_domains =

defer_transports =

disable_dns_lookups = no

What do I have wrong on main.cf for it not send the messages to the internet

Thanks
