Do you need these mail server settings?

You can use the mail server settings in this article to manually set up your email app to send and receive email with an iCloud email account. However, you shouldn't need to do that if you meet iCloud system requirements and can use any of these setup methods:

• Use iCloud Preferences on your Mac in OS X Lion 10.7.4 or later.
• Use iCloud for Windows on your PC in Microsoft Windows with Outlook 2010 through Outlook 2016. Set up two-factor authentication and, if needed, generate an app-specific password* to use for iCloud Mail.
• Use iCloud settings on your iPhone, iPad, or iPod touch with iOS 7 or later.

Mail server settings

Refer to your email app's documentation for information about how to use these settings. iCloud Mail uses the IMAP and SMTP standards supported by most modern email apps. iCloud does not support POP. If you set up an account using iCloud System Preferences or macOS Mail in 10.7.4 or later, you won't see these settings because they're automatically configured.

IMAP information for the incoming mail server

• Server name: imap.mail.me.com
• SSL Required: Yes
  If you see an error message when using SSL, try using TLS instead.
• Port: 993
• Username: This is usually the name part of your iCloud email address (for example, emilyparker, not emilyparker@icloud.com). If your email client can't connect to iCloud using just the name part of your iCloud email address, try using the full address.
• Password: Generate an app-specific password.

SMTP information for the outgoing mail server

Mail Settings For Mac Mail

• Server name: smtp.mail.me.com
• SSL Required: Yes
  If you see an error message when using SSL, try using TLS or STARTTLS instead.
• Port: 587
• SMTP Authentication Required: Yes
• Username: Your full iCloud email address (for example, emilyparker@icloud.com, not emilyparker)
• Password: Use the app-specific password that you generated when you set up the incoming mail server.

Mac Mail Smtp Server Settings

* You only need to use an app-specific password if you’re manually setting up mail with your iCloud account in Windows, if you use Mac OS X Mail (10.7.4 and earlier), or if you use any other third-party mail client.
