Mark Lutz, for O'Reilly Media, Inc.

PyMailGUI is a multiwindow interface for processing email, both online and
offline. Its main interfaces include one list window for the mail server,
zero or more list windows for mail save files, and multiple view windows for
composing or viewing emails selected in a list window. On startup, the main
(server) list window appears first, but no mail server connection is attempted
until a Load or message send request. All PyMailGUI windows may be resized,
which is especially useful in list windows to see additional columns.

Note: To use PyMailGUI to read and write email of your own, you must change
the POP and SMTP server names and login details in the file mailconfig.py,
located in PyMailGUI's source-code directory. See section 11 for details.
