General Instructions for Setting Up Email Programs

The following are quick outlines of the setups in each program.  Follow the links in each setup to see
step-by-step instructions with screenshots.  Contact your Internet Service Provider (ISP) for specific
names and values to be used in these setups.

Each program has settings for the
From address that will appear in your emails (usually called just
"Email Address"), and either the
Return Address, or the Reply-To address.  The Return Address is
used by the mail-transport system.  It is like the Return Address on an envelope, but it is not normally
seen by recipients.  The Reply-To address is added to the headers on your outgoing mail, and is a bit
more visible to recipients.  Either one works to set the To address when the recipient hits the Reply
button.

Incoming and outgoing servers are set up separately, although they can be the same.  Usually the
name of the server indicates its function, e.g. pop.mail.yahoo.com is the general name for any one of
several POP mail servers at yahoo.  POP is short for Post Office Protocol, a widely used method on
servers from which you retrieve your incoming mail.

Authentication is required to keep strangers out of your mailbox.  Your incoming mail server will
require a
login name and a password.  This login name is often not the same as your email name.

Outgoing mail is handled usually by SMTP servers, like smtp.mail.yahoo.com.  Authentication is
required to keep spammers from sending mail using your name.  Most ISPs set things up so that one
login and password works for both POP and SMTP.

Some setups are a little confusing on the difference between authentication of your identity and
security of the communications link between your computer and your ISP.  Authentication proves your
identity, assuming your password hasn't been stolen.  SSL and other security protocols encrypt
everything going out of your computer, including your password, thus protecting you from wiretaps,
"packet sniffers", "war drivers", and various other Internet criminals.  Check with your ISP, and use
whatever method they offer.
