1. This article walks you through the steps for setting up the following versions: Mail 11.2 on OS X El Capitan; Mail 11.2 on macOS Sierra (10.12) Mail 11.5 on macOS High Sierra (10.13.6).

This makes them accessible entirely offline and allow Spotlight to index them for easy search. However, if you have gigabytes of emails in your Gmail account or elsewhere, you may.

In this article, we'll show you how to set up email in Apple Mail on your Mac.

To tell Apple Mail the location of your IONOS mailboxes on the IMAP server:

Up to macOS El Capitan 10.11:

• Open App Mail on your Mac.
• Click Mail > Accounts.
• Select the desired email account in the left sidebar.
• Click on the More Options button. A new window opens.
• Enter the value INBOX in the field Path prefix and finish your entry with OK.

From macOS Sierra 10.12 and later:

• Click on Mail > Settings > Accounts tab > Server Settings tab.
• Click the Advanced IMAP Settings button in the Incoming Email Service (IMAP) field.
• Enter the value INBOX in the IMAP path prefix field and finish your entry with OK.

Setting Default Mailboxes in the Mail App

Apple Mail uses six default mailboxes in an email account: Inbox, Advertising, Sent, Drafts, Archive, and Trash. Use the mailbox behavior settings to control which mailboxes and where - on the mail server or locally - are used for this purpose.

If you use an IMAP mailbox on a mail server, you can access it from any device on which you have set up the e-mail account. If you are using a local mailbox, you can only access it on this machine.

To manage the default mailboxes for versions up to macOS El Capitan 10.11

• Open the Mail app on your Mac.
• Highlight the Inbox.
• Select Mailbox > New Mailbox from the menu bar and create a mailbox for Advertising, Sent, Drafts, Archive, and Trash.
• Select one of the mailboxes you just created.
• Use Mailbox > Use this Mailbox as to assign the appropriate function.
• Repeat step 5 for all mailboxes created in step 3.

To manage the default mailboxes for versions macOS Sierra 10.12 and later:

• Open the Mail app on your Mac.
• Click Mail > Settings > Accounts tab > Mailbox Behavior tab.
• Select the desired email account in the left sidebar.
• Use the list boxes to set the desired destination mailbox.
  Optional: For Spam and Deleted Mails, change the period after which the folder contents are deleted.
