\section{Standard Module \sectcode{mailbox}}
\label{module-mailbox}
\stmodindex{mailbox}


This module defines a number of classes that allow easy and uniform
access to mail messages in a (\UNIX{}) mailbox.

\begin{classdesc}{UnixMailbox}{fp}
Access a classic \UNIX{}-style mailbox, where all messages are contained
in a single file and separated by ``From name time'' lines.
The file object \var{fp} points to the mailbox file.
\end{classdesc}

\begin{classdesc}{MmdfMailbox}{fp}
Access an MMDF-style mailbox, where all messages are contained
in a single file and separated by lines consisting of 4 control-A
characters.  The file object \var{fp} points to the mailbox file.
\end{classdesc}

\begin{classdesc}{MHMailbox}{dirname}
Access an MH mailbox, a directory with each message in a separate
file with a numeric name.
The name of the mailbox directory is passed in \var{dirname}.
\end{classdesc}

\subsection{Mailbox Objects}
\label{mailbox-objects}

All implementations of Mailbox objects have one externally visible
method:

\begin{funcdesc}{next}{}
Return the next message in the mailbox, as a \class{rfc822.Message} object.
Depending on the mailbox implementation the \var{fp} attribute of this
object may be a true file object or a class instance simulating a file object,
taking care of things like message boundaries if multiple mail messages are
contained in a single file, etc.
\end{funcdesc}
