Last night, I updated to OS Big Sur 11.4 and it messed up my Mail accounts.
Now, for my various email accounts, I have a Sent mailbox and a Sent folder, a Draft Mailbox and a Draft folder, and a Trash mailbox and a Trash folder. I cannot delete the folders. Why not?

Those are all the mailboxes on your email provider's server. Since those are the default mailboxes, the server won't let you delete them (at least I have never seen any email service allow deleting them).
Mail shows what is on every account under the account header.
You can add what you want to access easily in the Favorites section
Why do I have a mailbox and a folder for the same items in Apple mail?
