Email spam problem

I have a server running Postfix on CentOS 6.5 and I think the permissions need tightening up to prevent the mail server sending messages other than from domains on the server

I need someone familiar with Postfix who can set it up so forms on the web server, mail etc still work but the mail server can't be used by other people to send spam.
