I have a a web server that needs to send emails, but not recieve them. I have installed postfix (it came with nagios, also installed on this server) and now I need to make sure that my server does not get used as a spam server.

What steps do I need to take to ensure that this does not happen?

What additional security measures do I need to put in place?

Server is Ubuntu 10.4
