Addressing messages

You can use three types of addresses in the ``To'' header line of a message to make sure it gets to the correct person: login names, network addresses, and aliases.

• If you are sending a message to someone who works on the same computer as you, that person's address is their login name.

• If your computer is part of a network of computers, and you are sending a message to someone on a different computer, you have to include the network address for the person's home computer in addition to their login name. For more information on networks and network addresses see ``Addressing mail to users on other systems''.

• If you routinely send mail to a certain group of people, it may be advantageous to use a mail alias.
