What is the current version of IMAP used for email access?

• A. IMAP3
• B. IMAP5
• C. IMAP4
• D. IMAP2

Answer: (C)

The current version of the Internet Message Access Protocol (IMAP) used for email access is IMAP4. This version, specified in RFC 3501, provides several enhancements over its predecessors, primarily allowing users to manage their email more effectively on a remote mail server. IMAP4 enables features such as the ability to manipulate messages (including deletion, organization into folders, etc.) directly on the server, which is particularly useful for users accessing email from multiple devices, as it maintains the integrity of the mailbox across sessions. In contrast, earlier versions like IMAP2 and IMAP3 are outdated and did not offer the full range of functionalities that modern users require. IMAP5 does not exist as a recognized version in the development of the protocol. Thus, IMAP4 remains the standard in email access protocols today due to its robustness and features designed to enhance user experience and email management.
