Mac OS X 10.5 Mail Setup

This tutorial will show you how to change the settings for your mail account within OS X’s built-in mail program, Mail.

This example is for an email address ending in If you have another domain with us, just replace your with your domain name.

Select Mail, then Preferences

  1. Once you’ve opened Mail, click on the menu labeled “Mail,” and select “Preferences.”
  2. Next, you’re presented with a window which contains three tabs, “Account Information, “Special Mailboxes,” and “Advanced.” First, let’s look at the “Account Information” tab.
    • The “Account type” was determined when you set up the account. You cannot change it unless you delete this account and create a new one. The account type is “POP.”
    • “Description” can be whatever you like, but it is recommended that you use something descriptive. This is just the description listed in Mail’s list of email accounts.
    • “Email Address” should be your email address.
    • “Full Name” can be your name, or whatever text you’d like to be seen as your name when you send email.
    • “Incoming Mail Server” should be “”
    • “User Name” should be your full email address (
      This e-mail address is being protected from spambots, you need JavaScript enabled to view it
    • “Password” is the password for your login name.

    Note: to add additional mail accounts, click the “+” button on the lower-left.

    • You can edit the Outgoing Mail Server by opening the Outgoing Mail Server (SMTP) pull-down menu, selecting “Edit server list,” then selecting the “Advanced” tab.
      1. The “Server Name” should be “”
      2. The “Server port” should be “25” or “2525”, if you are on DSL with “Use Secure Sockets Layer (SSL) NOT checked.
      3. Authentication should be “password” and the “User Name” should be your full email address and “Password” should be your password.

  3. Next, there are the “Special Mailboxes”
    • We keep a copy of every message we send from Mail.
    • We keep our deleted messages in a separate folder, but we remove them from Mail each time we quit the program, so we save hard drive space on our computer.

  4. Last, please take a look at the “Advanced” options.
    • “Enable this account” means that you will be able to send and receive mail from this group of mail settings.
    • “Include this account when automatically checking for new mail” means exactly what it says.
    • “Remove copy from server after retrieving a message” means that Mail will delete every message you download from after it’s been downloaded, and after the time specified by the pulldown menu just below that checkbox. We have set our OS X Mail program to delete the messages right away. That way mail will not pile up and it will keep your mail clear for new mail.
    • You can use the “Remove now” button to delete any old mail on the server that’s sitting there right now, if you wish.
    • “Prompt me to skip messages over [ ] KB” will let you tell Mail to not download messages larger than a certain size. This is great if you are on dialup and do not want to get large attachments. This will tell Mail to not download any particular message exceeding a certain file size. If you don’t want to use it, leave the field blank.
    • Incoming mail port should be 110.
    • Authentication should be set to “Password.”

    For more information about the behavior of each of these advanced options, click on the “?” button in the lower-right corner of this window.

That’s it! Press “OK” and close the account window.
