Why each option
IMAP allows clients to view and manage email stored on the server without downloading messages locally, unlike POP3 which retrieves and removes them.
IMAP (Internet Message Access Protocol) keeps messages on the mail server and lets clients read, flag, move, and delete them remotely. This server-side management means multiple devices can stay synchronized and messages are never required to be downloaded. It operates on port 143 (or 993 for IMAP over SSL).
SNMP (Simple Network Management Protocol) is used for monitoring and managing network devices, not for accessing email.
POP3 (Post Office Protocol 3) downloads email from the server to the local machine and typically deletes it from the server afterward, which is the opposite of the behavior described.
SMTP (Simple Mail Transfer Protocol) is used for sending email between servers, not for client access to a mailbox.
