Hi there,
Welcome to the board!
Really depends on what you are asking here. What type of email are we talking about here? POP? IMAP? Exchange Server? Depending on what you have, some options might be to either forward your emails in your account to another account accessible at your home pc, or copy all your emails to a file then transfer to home pc, or setup a duplicate/mirror account on your home pc (barring you don't delete the messges from your server once you d/l them at your work email). And we do not yet know what email client you are using either.
