SourceForge doesn't choke on this batch :-)
I'm not entirely sure this is 100% correct. The patch changes an
\index{persistency} to \index{presistence}, and I don't know what \index{}
does. But it seems to do so persi--er, consistently, so I hope it isn't a
problem.

|
\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 minimal 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 command, 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.
