You should use DNSBL to block most spammers. You can change smtp port 25, otherwise you never receive emails.

In mail server manager UI -> SMTP-> bindings you can control on which ports SMTP is running.

By default all is configured as is best for most users, you just need to create domains and users, thats all you need to do.
