I mentioned this.

With POP3 and maildir resource for local storage this is the case.

With POP3 and old KMail mixedmaildir resources some folders could also 
be mbox folders, but I believe maildir format was standard there as 
well.

With IMAP this does not work. That I did not mention, but John spoke 
about POP3. With IMAP some command line tools for IMAP mailbox handling 
could work.

Best,
