postfix

I am installing postfix and I am confused what to put for the system mail name. It has an exmaple that sais use "example.org" if a mail address on the system is "[email protected]" but it also sais that the mail name should be the FQDN.

my hostname is "mercury" and my FQDN is "mercury.pacificseatheat.org", so should I use "pacificseatheat.org" or "mercury.pacificseatheat.org" for the system mail name?

Thanks
