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 email 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 workflows.
Developers should learn IMAP when building email clients, integrating email functionality into applications, or automating email processing tasks, as it provides robust access to email data. It is essential for scenarios requiring real-time email synchronization, such as mobile apps or webmail services, and for implementing features like server-side filtering or email archiving systems.
