Which is an email protocol that retrieves email without deleting the email and its attachments from the server? Simple Mail Transfer Protocol (SMTP)

Internet Message Access Protocol (IMAP)

Post Office Protocol version 3 (POP 3)

Simple Network Management Protocol (SNMP)

Internet Message Access Protocol (IMAP)

Explanation:

The "Internet Message Access Protocol" or IMAP was created by Mark Crispin at the Stanford Knowledge Systems Laboratory. It allows a person to access his email from his local server. In comparison to the Post Office Protocol Version 3 (POP 3), which deletes the emails once they are downloaded, the IMAP allows the contents to be saved on the server. The email will only be deleted if the user intends to do so.
