BT folders not synched

Having just started using this and sent and received all my inbox, it has not synched my yahoo folders where on the server I have moved emails into, or given rules for certain emails to go into them automatically (using, it has only synched my inbox.
This is POP3.
Can I get these folders synched?

Hello, POP3 accounts do not synchronise your folders with the server, the POP3 protocol is designed to download only the new unread mail on the server, first sync can only synchronise your current inbox items and fetch new unread emails on the server.

If you’d like to synchronise your folders with the server you’d have to setup the account as IMAP rather than POP3.
