Determine the implementation method

There are two protocols for reading emails:POP3andIMAP, the difference is:The POP3protocol allows email clients to download emails on the server, but operations on the client will not be fed back to the server.IMAPProvides two-way communication between webmail and email clients. Operations on the client will be fed back to the server. For operations on emails, the emails on the server will also take corresponding actions.

The requirement requires that after processing the user's email, the email should be marked as processed, so theIMAPprotocol is selected.
