%the imaplib ``chapter''.
\section{\module{poplib} ---
POP3 protocol client}
\declaremodule{standard}{poplib}
\modulesynopsis{POP3 protocol client (requires sockets).}
\indexii{POP3}{protocol}
This module defines a class, \class{POP3}, which encapsulates a
connection to an POP3 server and implements protocol as defined in
\rfc{1725}. The \class{POP3} class supports both the minmal and
optional command sets.
A single class is provided by the \module{poplib} module:
\begin{classdesc}{POP3}{host\optional{, port}}
This class implements the actual POP3 protocol. The connection is
created when the instance is initialized.
If \var{port} is omitted, the standard POP3 port (110) is used.
\end{classdesc}
One exception is defined as an attribute of the \module{poplib} module:
\begin{excdesc}{error_proto}
Exception raised on any errors. The reason for the exception is
passed to the constructor as a string.
\end{excdesc}
\subsection{POP3 Objects \label{pop3-objects}}
All POP3 commands are represented by methods of the same name,
in lower-case; most return the response text sent by the server.
An \class{POP3} instance has the following methods:
\begin{methoddesc}{getwelcome}{}
Returns the greeting string sent by the POP3 server.
\end{methoddesc}
\begin{methoddesc}{user}{username}
Send user commad, response should indicate that a password is required.
\end{methoddesc}
\begin{methoddesc}{pass_}{password}
Send password, response includes message count and mailbox size.
Note: the mailbox on the server is locked until \method{quit()} is
called.
\end{methoddesc}
\begin{methoddesc}{apop}{user, secret}
Use the more secure APOP authentication to log into the POP3 server.
\end{methoddesc}
\begin{methoddesc}{rpop}{user}
Use RPOP authentication (similar to UNIX r-commands) to log into POP3 server.
\end{methoddesc}
\begin{methoddesc}{stat}{}
Get mailbox status. The result is a tuple of 2 integers:
\code{(\var{message count}, \var{mailbox size})}.
\end{methoddesc}
\begin{methoddesc}{list}{\optional{which}}
Request message list, result is in the form
\code{(\var{response}, ['mesg_num octets', ...])}. If \var{which} is
set, it is the message to list.
\end{methoddesc}
\begin{methoddesc}{retr}{which}
Retrieve whole message number \var{which}. Result is in form
\code{(\var{response}, ['line', ...], \var{octets})}.
\end{methoddesc}
\begin{methoddesc}{dele}{which}
Delete message number \var{which}.
\end{methoddesc}
\begin{methoddesc}{rset}{}
Remove any deletion marks for the mailbox.
\end{methoddesc}
\begin{methoddesc}{noop}{}
Do nothing. Might be used as a keep-alive.
\end{methoddesc}
\begin{methoddesc}{quit}{}
Signoff: commit changes, unlock mailbox, drop connection.
\end{methoddesc}
\begin{methoddesc}{top}{which, howmuch}
Retrieves the message header plus \var{howmuch} lines of the message
after the header of message number \var{which}. Result is in form
\code{(\var{response}, ['line', ...], \var{octets})}.
\end{methoddesc}
\begin{methoddesc}{uidl}{\optional{which}}
Return message digest (unique id) list.
If \var{which} is specified, result contains the unique id for that
message in the form \code{'\var{response}\ \var{mesgnum}\ \var{uid}},
otherwise result is list \code{(\var{response}, ['mesgnum uid', ...],
\var{octets})}.
\end{methoddesc}
\subsection{POP3 Example \label{pop3-example}}
Here is a minimal example (without error checking) that opens a
mailbox and retrieves and prints all messages:
\begin{verbatim}
import getpass, poplib
M = poplib.POP3('localhost')
M.user(getpass.getuser())
M.pass_(getpass.getpass())
numMessages = len(M.list()[1])
for i in range(numMessages):
for j in M.retr(i+1)[1]:
print j
\end{verbatim}
At the end of the module, there is a test section that contains a more
extensive example of usage.
