// RFC 2193 IMAP4 Mailbox Referrals
// http://tools.ietf.org/html/rfc2193
// 4.1. SELECT, EXAMINE, DELETE, SUBSCRIBE, UNSUBSCRIBE, STATUS and APPEND
// Referrals
// An IMAP4 server MAY respond to the SELECT, EXAMINE, DELETE,
// SUBSCRIBE, UNSUBSCRIBE, STATUS or APPEND command with one or more
// IMAP mailbox referrals to indicate to the client that the mailbox is
// hosted on a remote server.
// 4.2. CREATE Referrals
// An IMAP4 server MAY respond to the CREATE command with one or more
// IMAP mailbox referrals, if it wishes to direct the client to issue
// the CREATE against another server. The server can employ any means,
// such as examining the hierarchy of the specified mailbox name, in
// determining which server the mailbox should be created on.
// 4.3. RENAME Referrals
// An IMAP4 server MAY respond to the RENAME command with one or more
// pairs of IMAP mailbox referrals. In each pair of IMAP mailbox
// referrals, the first one is an URL to the existing mailbox name and
// the second is an URL to the requested new mailbox name.
// 4.4. COPY Referrals
// An IMAP4 server MAY respond to the COPY command with one or more IMAP
// mailbox referrals. This indicates that the destination mailbox is on
// a remote server. To achieve the same behavior of a server COPY, the
// client MAY issue the constituent FETCH and APPEND commands against
// both servers.
