POP3 has no concept of folders other than INBOX so /sent, /trash, /junk aren't visible and you can't sync them for offline use. Zimbra Desktop uses an XML interface to scrape the content from Yahoo Webmail and it's cached for offline use, but Mail.app can't do this. IMAP4 is what you need, but if it's not available the only solution is to change mail provider to one that does or wait until Yahoo succumbs to peer/user pressure and improves their service. There's a petition on facebook requesting IMAP support, but no signs of activity from Yahoo. |
