Returns an IMAP stream on success and FALSE on error. 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.
A mailbox name consists of a server part and a mailbox path on
this server. The special name INBOX stands for the current users
personal mailbox. 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. Mailbox names that contain international characters
besides those in the printable ASCII space have to be encoded
with imap_utf7_encode().
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
