relayhost =gives you the possibility of using the mail server on a machine for the sole purpose of sending mail to another mail server. The other server is the one that really sends it out into the Internet. This might be used in large organizations where there may be divisions of the company that work in remote locations with different types of Internet connection. There are cases where workers are accessing Internet from some type of broadband connection. If the mail were to go out directly, new anti-spamming techniques might tag this mail as spam (and often do!). This way, a branch office of an organization might configure Postfix to have a relay host which is at the main office with a permanent high-speed Internet connection. So you could use a hostname or IP address here as well.
