The following is a list of variables that influence how the mail is fetched. You would normally not need to set or change any of these variables.
mail-source-crash-box ¶File where mail will be stored while processing it. The default is
~/.emacs-mail-crash-box.
mail-source-delete-incoming ¶If non-nil, delete incoming files after handling them. If
t, delete the files immediately, if nil, never delete any
files. If a positive number, delete files older than number of days
(the deletion will only happen when receiving new mail). You may also
set mail-source-delete-incoming to nil and call
mail-source-delete-old-incoming from a hook or interactively.
mail-source-delete-old-incoming-confirm ¶If non-nil, ask for confirmation before deleting old incoming
files. This variable only applies when
mail-source-delete-incoming is a positive number.
mail-source-directory ¶Directory where incoming mail source files (if any) will be stored. The
default is ~/Mail/. At present, the only thing this is used for
is to say where the incoming files will be stored if the variable
mail-source-delete-incoming is nil or a number.
mail-source-incoming-file-prefix ¶Prefix for file name for storing incoming mail. The default is
Incoming, in which case files will end up with names like
Incoming30630D_ or Incoming298602ZD. This is really only
relevant if mail-source-delete-incoming is nil or a
number.
mail-source-default-file-modes ¶All new mail files will get this file mode. The default is #o600.
mail-source-movemail-program ¶If non-nil, name of program for fetching new mail. If
nil, movemail in exec-directory.
