Which two settings are correct for an email address ending in @iCloud.com?

An email address ending in @iCloud.com is designed to utilize IMAP (Internet Message Access Protocol) as the account type for the incoming mail server. IMAP is favored for iCloud email because it allows users to access their email messages from multiple devices while keeping messages synchronized. Changes made on one device (such as reading, deleting, or moving messages) are reflected on all other devices accessing the same email account. This capability is essential for users who check their email on various devices like iPhones, iPads, and Macs.

In contrast, the use of POP (Post Office Protocol) is less suitable for iCloud email, as POP downloads messages to a single device and generally doesn’t sync changes, which can lead to inconsistencies if the email is accessed from multiple devices.

Regarding the outgoing mail server SMTP settings, using port 587 is secure and recommended for sending emails via iCloud, supporting modern encryption protocols to ensure safe transmission of email data. Port 25, on the other hand, is often blocked by many Internet Service Providers to combat spam, making it an inadequate choice for sending emails from an iCloud address. Therefore, using port 587 aligns with best practices for secure and reliable email delivery.
