This module defines three classes, \class{IMAP4}, \class{IMAP4_SSL}
and \class{IMAP4_stream}, which encapsulate a
connection to an IMAP4 server and implement a large subset of the
IMAP4rev1 client protocol as defined in \rfc{2060}. It is backward
compatible with IMAP4 (\rfc{1730}) servers, but note that the
\samp{STATUS} command is not supported in IMAP4.
Three classes are provided by the \module{imaplib} module, \class{IMAP4} is the base class:

There's also a subclass for secure connections:
\begin{classdesc}{IMAP4_SSL}{\optional{host\optional{, port\optional{, keyfile\optional{, certfile}}}}}
This is a subclass derived from \class{IMAP4} that connects over an SSL encrypted socket
(to use this class you need a socket module that was compiled with SSL support).
If \var{host} is not specified, \code{''} (the local host) is used.
If \var{port} is omitted, the standard IMAP4-over-SSL port (993) is used.
\var{keyfile} and \var{certfile} are also optional - they can contain a PEM formatted
private key and certificate chain file for the SSL connection.
