 Net::Gmail::IMAP::Label provides a proxy that sits between an IMAP client and
 Gmail's IMAPS server and adds GMail labels to the X-Label header. This proxy
 uses the Gmail IMAP extensions.

 To use this proxy, your e-mail client will need to connect to the proxy using
 the IMAP protocol (without SSL).
