IMAP
Definition
The Internet Message Access Protocol (IMAP) is an Internet standard protocol used by email clients to retrieve email messages from a mail server over a TCP/IP connection. IMAP allows for the management of email directly on the server.
Why It Matters
IMAP is the modern standard for email access. Because it keeps emails on the server, it allows you to access and manage your email from multiple devices (phone, laptop, webmail) and have everything stay in sync. Actions like reading, deleting, or moving an email are reflected on all devices.
Contextual Example
When you configure your phone's email app, you typically enter your email provider's IMAP server address. The app then uses IMAP to fetch your folders and messages from the server.
Common Misunderstandings
- IMAP is different from POP3. POP3 typically downloads emails to your device and deletes them from the server, making multi-device access difficult.
- IMAP is a protocol for receiving email. SMTP is the protocol for sending email.
