Answer:
IMAP keeps email on an email server by default
Explanation:
IMAP by default can keep the email in the server, this is so helpful because we can get the email in any location, this is the difference with POP3.
POP3 stores the email in the server, but when we get the email with our application, the server deletes all the information, although we can do a configuration in the settings called Keep email on the server.
