Question : Fetchmail not retrieving sent & junk folder

I've setup fetchmail on ubuntu machine to retrieve emails via pop3 from ISP.

However, I've only managed to retrieve those emails in INBOX. While I actually need to retrieve all emails, including SENT, JUNK and TRASH.

Can you please guide me on how to do this?
Thank You
