[CentOS] Postfix SMTP auto on remote relay server

Does anyone know how to configure Postfix to use SMTP authentication
on a relay host?

i.e. I have a Linux server, running PostFix on an ADSL line with a
dynamic IP. Thus I can't just send out emails from this server but
need to relay it via our ISP's SMTP server, which is very unreliable.
Now I want to relay the email via another SMTP server where a user
account with the same domain has already been setup, but I got no idea
how to get it to work on SMTP authenticiaion.

Any suggestions?

Kind Regards
