To set up working with Icloud mail via IMAP, you need to create an app-specific password. You can find detailed instructions on how to do this here.

Below are the settings you need to adjust after creating the app-specific password for your email:

• __setting__email__ - Your email identifier, for example (afina@icloud.com)
• __setting__password__ - Your app-specific password
• __setting__imap__host__ - imap.mail.me.com
• __setting__imap__port__ - 993
