Setting up a POP3 account on OS X 10.4 (Tiger)
Summary:
If you're not running OS X Tiger, your screens may be slightly different.
Here is a quick summary of the important settings to use:
Account Type: POP
Email Address: username@kattare.com (your full email address)
Incoming Mail Server: mail.kattare.com
Incoming Mail User Name: (your POP3 username as displayed in the Email
Management here.)
Incoming Mail Password: (your POP3 password from the same page.)
Incoming Mail Security: Use SSL, authentication; PASSWORD
Outgoing Mail Server: mail.kattare.com, check USE AUTHENTICATION
Outgoing Mail User Name: (your POP3 username as displayed in the Email
Management here.)
Outgoing Mail Password: (your POP3 password from the same page.)
Account Information; Outgoing Mail Server Settings: Server Port 2525
Advanced; Incoming Mail Port: 995
Advanced; check REMOVE COPY FROM SERVER AFTER RETRIEVAL, select RIGHT
AWAY
And here are the step by step instructions:
The first time you start up Mail.app it will automatically jump into the
New Account wizard. If this is not the first time you have run
Mail.app, you can get to the wizard by clicking FILE, then ADD ACCOUNT.

This is roughly what it should look like. Just click CONTINUE.

On the General Information page, you want to select an Account Type of
POP, plug in anything you want for the Account Description. Then plug
in your Full Name and your Email Address and click CONTINUE.

On the Incoming Mail Server page plug in mail.kattare.com as the
Incoming Mail Server. Then plug in your POP3 User Name and Password as you
have been told by your local Systems Administrator, IT Guru, or the Kattare
Members Section Email
Management Page.

On the Incoming Mail Security page, check the Use Secure Sockets Layer
checkbox and select Password as the Authentication type.

On the Outgoing Mail Server page, plug in mail.kattare.com as the
Outgoing Mail Server, then check the Use Authentication checkbox and fill
in your User Name and Password exactly like you did on the Incoming Mail
Server page.

On the Outgoing Mail Security page you will want to check the Use
Secure Sockets Layer checkbox and select the Password Authentication
type.

On the Account Summary page you can review your settings. Make sure
everything looks right before clicking Continue.

If all went as planned, you will reach this Conclusion page. Click
Done and continue to the Advanced Preferences instructions below.

Despite having completed the wizard, there are still a couple of settings that
will need to be changed to ensure trouble-free operation. To get started
click Mail, followed by Preferences as shown below.

On the Preferences page you will want to click on the Accounts
icon near the top left. Then you will want to select your new Kattare
account and click on the Account Information tab. Once you are on
the Account Information tab, click the Server Settings... button
below the Outgoing Mail Server dropdown.

On the Server Settings box you will want to change the Server port to
2525. Everything else should already be setup. Click OK
when you are finished.

Back on the Accounts page click on the Mailbox Behaviors tab.
We recommend the settings shown. Really these are all up to you.

Click on the Advanced tab on the Accounts page. You will
want to make sure that all of the three checkboxes are checked near the top and
on the drop down you will want to make certain that Right Away is
selected. Then you will want to double-check that the Port is set to
995 and the Authentication type is set to Password.

Once that is all done and everything checks out, go ahead and close the
Preferences window. It will prompt you to save your changes, which you
definitely want to do.
Happy Emailing!
