Set up Mac mail with IMAP

This article applies to recent versions of SmarterMail. View articles for SmarterMail 16.x and earlier.

IMAP is a protocol that keeps all messages and folders on the server. In addition, IMAP idle is an optional feature of the IMAP protocol that pushes all new messages to Outlook as they are received by the mail server. Unlike POP, IMAP offers two-way communication between your SmarterMail mailbox and your email client(s). This means when you log in to the SmarterMail Web interface, actions you performed on email clients and mobile devices will automatically appear in the Web interface (and vice versa). IMPORTANT: It is recommended that you avoid putting sub-folders under your Inbox as IMAP synchronization with most email clients is unreliable. This is a limitation of mail clients and NOT SmarterMail. While the SmarterMail web interface does allow you to create folders in your inbox, realize that those folders may not appear in your email client.

Follow these steps to set up Apple Mail to sync with SmarterMail via IMAP :

  1. On your Mac, open System Preferences.
  2. Click Internet Accounts.
  3. Click Add Other Account...
  4. Select Add a Mail account and click Create.
  5. Complete the full name, full email address and password fields.

  8. For the Incoming Mail Server Info, select the IMAP for account type. Complete the required fields: Mail Server, User Name (enter your full email address), and Password.
  9. Click Next.
  10. For the Outgoing Mail Server Info, fill in the required fields: SMTP Server (, User Name (enter your full email address), and Password.
  11. Click Create.
  12. Your account is now created and you'll see an account summary page.

Yes, using is a standard set up for an outbound mail server. Chances are that the issue is step 12 where you configure SMTP authentication. You will need to check with your hosting company or your IT admin for the correct configuration.
