IMAP
IMAP (Internet Message Access Protocol) is a standard email protocol used for retrieving and managing email messages from a mail server. It allows users to access their emails from multiple devices while keeping messages stored on the server, enabling synchronization across clients. Unlike POP3, IMAP supports folder management, message flagging, and server-side searches, making it ideal for modern email usage.
Developers should learn IMAP when building email clients, integrating email functionality into applications, or managing email systems, as it provides robust features for real-time email access and synchronization. It is essential for scenarios requiring multi-device support, server-side email organization, or advanced email handling in software like webmail services or mobile apps.
