c /**
* Opens an IMAP stream to a mailbox.
*
* This function can also be used to open streams to POP3 and
* NNTP servers, but some functions and features are only
* available on IMAP servers.
*
* @param string $mailbox A mailbox name consists of a server and a mailbox path on this server.
* The special name INBOX stands for the current users
* personal mailbox. Mailbox names that contain international characters
* besides those in the printable ASCII space have to be encoded with
* imap_utf7_encode.
*
* The server part, which is enclosed in '{' and '}', consists of the servers
* name or ip address, an optional port (prefixed by ':'), and an optional
* protocol specification (prefixed by '/').
*
* The server part is mandatory in all mailbox
* parameters.
*
* All names which start with { are remote names, and are
* in the form "{" remote_system_name [":" port] [flags] "}"
* [mailbox_name] where:
*
*
*
* remote_system_name - Internet domain name or
* bracketed IP address of server.
*
*
*
*
* port - optional TCP port number, default is the
* default port for that service
*
*
*
*
* flags - optional flags, see following table.
*
*
*
*
* mailbox_name - remote mailbox name, default is INBOX
