# IMAP

## **Introduction**

> By default, the Internet Message Access Protocol (IMAP) protocol works on Port 143 (unencrypted) or 993 (encrypted). IMAP allows online management of emails directly on the server and supports folder structures.\
> Thus, it is a network protocol for the online management of emails on a remote server.<br>
