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. 1. 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)

1. 1. 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. 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

1. Go ahead and change the Port Number to 465
2. Click the Save button on the bottom right
3. Close the Accounts window
4. 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
