When did POP and IMAP become a “legacy protocol?”

Yeah, but typically the difference is that you can't see IMAP as a backup. Whereas with POP3 (and not having your client set up to automatically delete emails on the server) you can.

With IMAP, when an email gets deleted by some client, other clients will also delete their local copies of that email. That won't happen with POP3.

But I haven't read either of the two protocols, so I'm not sure whether that's something required by the protocol or just a common behavior of clients.

This is not an IMAP feature, this is a client feature. There are plenty of clients that don’t sync deletes, if you don’t want to.

Or, just don’t delete your emails? If you delete a POP email from your client, it’s also gone for good.

Yeah, it's much better with POP3, when one client downloads everything it deletes it from the server /s

This isn't IMAP limitation, this is how clients implemented it. Nothing stops one to download every message over IMAP and never delete them.

Common POP I implementations let me leave things on the server indefinitely, for a chosen period, or to delete immediately on retrieval, leaving the local copy intact. Can you think of any IMAP implementations that allow that?
