problem with download emails (pop3)

Hi, I start to use eM Client, I use POP3, because I need to have emails in my computer and delete from provider. When I start, the client downloads only emails from inbox folder, so no sent emails, no other folders … I cannot use the client without my old emails, but I coulnt find a way to download them.  When I try it with IMAP all emails are downloaded, I don ́t know if it is impossible to download all email in POP3 sistem or what I am doing wrong. Thanks

POP will only access the Inbox on your mail server.

If you setup the account with IMAP and then copy the messages and folders to Local Folders, you can then delete the IMAP account and setup a POP3 account and still have all the messages and folders.
