Dear Giles,

I think you're searching for this.


$ cat /etc/postfix/main.cf
myorigin=yourdomain.com
relayhost=your.smarthost.com
smtp_sasl_auth_enable=yes
## you probably want to limit how postfix authenticates
# smtp_sasl_security_options=noanonymous
# smtp_sasl_mechanism_filter=login
smtp_sasl_password_maps=hash:/etc/postfix/relay_password
## if something doesn't work and you need detailed(!!) logs
#debug_peer_list=your.smarthost.com
#debug_peer_level=3
smtp_use_tls=yes
#inet_interfaces = loopback-only
#local_transport = error: disabled
unknown_local_recipient_reject_code = 450


$ cat /etc/postfix/relay_password
your.smarthost.com  yourusername:yourpassword

$ postmap /etc/postfix/relay_password
$ service postfix reload


You can check out the commented option in the man pages or
http://www.postfix.org/postconf.5.html
if you're interested later/have some spare time/if it doesn't work ;-)


Brgds
