This article will assist you with setting up Apple Mail, using IMAP, for your Hosted Mailbox. This article assumes you have macOS 10.12 (Sierra) or higher. To check your version, click on the Apple icon on the top left corner and then About this Mac.

1. Launch Mail. If Mail is not in your dock, Command (⌘) + Space Bar. Then type Mail in the Spotlight search. Press enter to launch the Mail application.
2. Within Mail, click Mail on the top left. Then select Add Account

            3.  In the pop-up window, select Other Mail Account

            4.  In the next screen, enter the following information:

                 Name: Enter your first and last name
                 Email Address: Example@reagan.com
                 Password: Enter your mailbox password

            5.  Select Sign In.

      6.  You will see an alert which says Unable to verify account name or password. Along with this alert, you will see more fields that require additional info

                 Fill in the following details:

                 Email Address: Example@reagan.com
                 User Name: Example@reagan.com (even though it says automatic, fill it in as shown)
                 Password: Your mailbox password
                 Account Type: IMAP
                 Incoming Mail Server: secure.emailsrvr.com
                 Outgoing Mail Server: secure.emailsrvr.com

Important Note:

Apple Mail will usually clear the User Name field after entering the Incoming and Outgoing Mail Server fields. Ensure your User Name is filled in with your email address after entering the server information and before clicking Sign in.

            7.  Click Sign In

            8.  Select the desired syncing options. You can leave the defaults on

           9.  Click Done

Next, we will configure your Mac to sync your various IMAP folders and prevent duplicate folders from showing up. We call this Folder Mapping; below are the steps to do so

1. Within Mail, click Mail on the top left. Then select Preferences

        2.  Select the Accounts tab at the top of the window, then select your IMAP email from the left pane

            3.  Select the Mailbox Behaviors tab

            4.  Click the Sent Mailbox dropdown and select the folder Sent

that's listed under your email address (not the folder listed under "On My Mac")

            5.  Click the Junk Mailbox dropdown and select the folder spam that's listed under your email address (not the folder listed under On My Mac)

            6.  Click the Trash Mailbox dropdown and select the folder Trash that's listed under your email address (not the folder listed under On My Mac)

Lastly, we will make sure our SMTP server settings are correct, as Apple Mail tends to change them automatically during setup

1. While still on the Accounts screen, click on the Server Settings tab, next to Mailbox Behaviors

            2.  Under Outgoing Mail Server SMTP, Uncheck the automatically manage connection                             settings. (Make sure you do it under SMTP, and not IMAP, as they have the same checkbox)                   This will unlock a new area below

    3.  Go ahead and change the Port Number to 465

    4.  Click the Save button on the bottom right

    5.  Close the Accounts window

    6.  Finally, go back to the Mail app. Your email should begin downloading shortly, if it hasn't already. Please wait 15 minutes for mail to download before troubleshooting any issues
