ACCOUNT1 is your email account. If it's POP account then usually it holds your emails that have been downloaded from the email server.
For imap accounts the emails might still be on the server, although it can be configured to store emails and download them to your computer for reading offline.
Local Folders is just a default set of email folders, to the best of my knowledge, that many email programs create to organize emails locally. Someone correct me if I'm wrong interpreting my understanding of Local Folders.
