Open up Mac OS X Mail 2.x and select Mail from the top menu
bar and click on Preferences.

Click on Accounts on the top of the window. Then click on
the
plus
sign, located at the bottom-left of the window, to create a new
account.
Select IMAP or POP from the Account Type:
drop-down menu (IMAP is strongly recommended).
In the Account Description: field, type a name that you will
use to identify the account. This can be helpful if you have several
accounts in OS X Mail and need to differentiate between them. For example,
a name like Mail@umd will be sufficient.
For Full Name:, type your name, as you would like people to
see it when they receive mail from you.
Type your e-mail address in the Email Address: field.
Click the Continue button.
For Incoming Mail Server:, type in the appropriate IMAP or
POP incoming mail server for your email account.
IMAP
If your e-mail account is a:
- Mail@UMD account, use mail.umd.edu
- WAM account, use imap.wam.umd.edu
- Glue account, use imap.glue.umd.edu
- Deans account, use imap.deans.umd.edu
POP
If your e-mail account is a:
- Mail@UMD account, use mail.umd.edu

- Glue account, use pop.glue.umd.edu
- Deans account, use pop.deans.umd.edu
In the User Name; field, type in the part of your address
that
precedes the @ sign in your e-mail address. For example, if your e-mail
address was jdoe@wam.umd.edu, your user name would simply be
jdoe.
Type in your password in the Password: field if you would
like OS X Mail to remember it each time you check your mail.
Click the Continue button.
In the Outgoing Mail Server: field, type in the outgoing
mail server for your email account.
PLEASE NOTE: If you use an Internet service provider
(ISP) other than the University of Maryland for Internet access, you
must use your ISP's SMTP server (contact your Internet Service Provider
for more information on this) instead of one of the servers listed below.
- Mail@UMD account, use mail.umd.edu
- WAM account, use smtp.wam.umd.edu
- Glue account, use smtp.glue.umd.edu
- Deans account, use smtp.deans.umd.edu
If you use mail.umd.edu as your outgoing mail server, place
a check next to use Use
Authentication, otherwise leave it unchecked.
If you use mail.umd.edu as your outgoing mail server,
fill in the User Name: and Password: fields with your
account information, otherwise leave the fields blank.
Click the Continue button.
An Account Summary will appear, check it for accuracy. Click
the Continue button.
Click the Done button.
Click the Advanced button. Place a check next to Use
SSL.
Click the Account Information button. If your
Accounts window looks similar to the screen below,
close the window.

You will be asked to save the changes. Click on
Save.
Setup is now complete. Your mail folders should appear to the side
of
the window, and you should be able to read and send messages at this
time.
