1. Select Mail / Preferences, click the Accounts button, located at the top of the window and click once on your IMAP account, as it appears in the Accounts list.

2. Click the Mailbox Behaviors tab, clear all of the check boxes and close the Accounts window.

3. When prompted to save your changes, click the Save button.

4. In your IMAP folder, located in the Mailboxes pane (select View / Show Mailboxes to display the pane if it’s not there), do the following:

• Click once on the Sent, Drafts, Spam, or Trash folder.

• Select Mailbox / Use This Mailbox For.

• Select Sent, Drafts, Junk, or Trash from the resulting list in the sub-menu.

5. The selected folder will disappear from your IMAP list, and will now reappear as the corresponding Mac Mail folder.
