Which protocol is defined for a more powerful mail server access allowing multiple mail server access?

The Internet Message Access Protocol (IMAP) is a protocol that allows users to access their emails on a mail server and is designed specifically for more powerful mail server access. One of the key features of IMAP is that it enables multiple mail server access simultaneously. This means users can manage their email directly on the server without needing to download it to their local device.

With IMAP, users can organize, delete, or mark messages as read while retaining all interactions on the server. This is particularly useful for individuals who access their email from multiple devices, as changes made on one device are reflected across all others. Additionally, IMAP supports complex mailbox structures, allowing users to create folders and subfolders to better organize their emails.

Unlike IMAP, the Post Office Protocol (POP) is generally more limited, as it downloads emails to a local device and typically removes them from the server. Simple Mail Transfer Protocol (SMTP) is primarily used for sending emails rather than accessing them. File Transfer Protocol (FTP) is used for transferring files between computers and does not pertain to email management.
