MH & nmh: Email for Users & Programmers
Email addressing varies. How you do it on your computer and your
network might be different than what I show here. Basically,
though, there are two kinds of email addresses:
If you're sending a message to someone who has an account on
your computer, address it to that person's username (login
name). For instance, if Marty Waters logs on to his account with
mwaters, you can address his mail to mwaters.
If you're sending a message to someone who reads mail on another
computer, you'll usually need to include that computer's name in
your address. Two forms of addresses are pretty common:
Internet addresses have a username, followed by an at sign (@)
and the other computer's hostname. For example, if Edie
Nisbaum's username is edie and her computer is
named giraffe.zoo.utx.edu you'd address Internet mail
to her as firstname.lastname@example.org.
UUCP addresses have the other computer's name, followed by an
exclamation point (!) and then the username. If Sandi
Shore is sandis and her computer is named beach,
you might address her mail as beach!sandis.
Those address guidelines won't be right for everyone. If you
have questions, ask your system postmaster or administrator.
