  "*If non-nil this variable's value should be a list of strings 
or a list of lists.

If the value is a list of strings, the strings should name files
that VM will check for incoming mail instead of the default place
VM thinks your system mailbox is.  Mail will be moved from these
mailboxes to your primary inbox as specified by vm-primary-inbox,
using vm-crash-box as a waystation.

If the value is a list of lists, each sublist should be of the form

    (INBOX SPOOLNAME CRASHBOX)

INBOX, SPOOLNAME and CRASHBOX are all strings.

INBOX is the folder where you want your new mail to be moved when
you type 'g' (running vm-get-new-mail) in VM.  It is where you
will read the mail.

SPOOLNAME is where the mail system leaves your incoming mail,
e.g. /var/spool/mail/kyle.  It can also be a POP maildrop,
provided it can be matched by the value of vm-recognize-pop-maildrops.

    A POP maildrop specification has the following format:

       \"HOST:PORT:AUTH:USER:PASSWORD\"

    HOST is the host name of the POP server
    PORT is the TCP port number to connect to (should normally be 110).
    USER is the user name sent to the server.
    PASSWORD is the secret shared by you and the server for
    authentication purposes.  How is it used depends on the value of
    the AUTH parameter.  If the PASSWORD is \"*\", VM will prompt
    you for the password the first time you try to retrieve mail from
    maildrop.  If the password is valid, VM will not ask you for the
    password again during this Emacs session.

    AUTH is the authentication method used to convince the server you
    should have access to the maildrop.  Acceptable values are
    \"pass\", \"rpop\" and \"apop\".  For \"pass\", the PASSWORD is sent to
    the server with the POP PASS command.  For \"rpop\", the PASSWORD
    should be the string to be sent to the server via the RPOP
    command.  In this case the string is not really a secret;
    authentication is done by other means.  For \"apop\", an MD5 digest
    of the PASSWORD appended to the server timestamp will be sent to
    the server with the APOP command.  In order to use \"apop\" you
    will have to set the value of vm-pop-md5-program appropriately to
    point at the program that will generate the MD5 digest that VM
    needs.

CRASHBOX is the temporary file that VM uses to store mail in
between the SPOOLNAME and the INBOX.  If the system crashes or
Emacs dies while mail is being moved, and the new mail is not in
the SPOOLNAME or the INBOX, then it will be in the CRASHBOX.

There can be multiple entries with the same INBOX value, but a
particular SPOOLNAME should appear only once.  CRASHBOXes should
not be shared among different INBOXes, but you can use the same
CRASHBOX/INBOX pair with a different SPOOLNAME.

NOTE:  The values of vm-primary-inbox and vm-crash-box are ignored
when getting new mail if vm-spool-files is a list of lists.

vm-spool-files will default to the value of the shell
environmental variables MAILPATH or MAIL if either of these

Normally when a message attribute is changed. VM keeps the record

  "*Non-nil value should be a list of virtual folder definitions.

A virtual folder is a mapping of messages from one or more real folders
into what appears to be a single folder.  A virtual folder definition
specifies which real folders should be searched for prospective messages
and what the inclusion criteria are.

Each virtual folder definition should have the following form:

  (VIRTUAL-FOLDER-NAME
    ( (FOLDER-NAME ...)
      (SELECTOR [ARG ...]) ... )
    ... )

VIRTUAL-FOLDER-NAME is the name of the virtual folder being defined.
This is the name by which you and VM will refer to this folder.

FOLDER-NAME should be the name of a real folder.  There may be more than
one FOLDER-NAME listed, the SELECTORs within that sublist will apply to
them all.  If FOLDER-NAME is a directory, VM will assume this to mean that
all the folders in that directory should be searched.

The SELECTOR is a Lisp symbol that tells VM how to decide whether a message
from one of the folders specified by the FOLDER-NAMEs should be included
in the virtual folder.  Some SELECTORs require an argument ARG; unless
otherwise noted ARG may be omitted.

The recognized SELECTORs are:

   author          - matches message if ARG matches the author; ARG should be a
                     regular expression.
   and             - matches the message if all its argument
                     selectors match the message.  Example:
                        (and (author \"Derek McGinty\") (new))
                     matches all new messages from Derek McGinty.
                     `and' takes any number of arguments. 
   any             - matches any message.
   deleted         - matches message if it is flagged for deletion.
   edited          - matches message if it has been edited.
   filed           - matched message if it has been saved with its headers.
   forwarded       - matches message if it has been forwarded.
   header          - matches message if ARG matches any part of the header
                     portion of the message; ARG should be a
                     regular expression. 
   label           - matches message if message has a label named ARG.
   less-chars-than - matches message if message has less than ARG
                     characters.  ARG should be a number.
   less-lines-than - matches message if message has less than ARG
                     lines.  ARG should be a number.
   more-chars-than - matches message if message has more than ARG
                     characters.  ARG should be a number.
   more-lines-than - matches message if message has more than ARG
                     lines.  ARG should be a number.
   marked          - matches message if it is marked, as with vm-mark-message.
   new             - matches message if it is new.
   not             - matches message only if its selector argument
                     does NOT match the message.  Example:
                       (not (deleted))
                     matches messages that are not deleted.
   or              - matches the message if any of its argument
                     selectors match the message.  Example:
                        (or (author \"Dave Weckl\") (subject \"drum\"))
                     matches messages from Dave Weckl or messages
                     with the word \"drum\" in their Subject header.
                     `or' takes any number of arguments.
   read            - matches message if it is neither new nor unread.
   recipient       - matches message if ARG matches any part of the recipient
                     list of the message.  ARG should be a regular expression.
   replied         - matches message if it has been replied to.
   sent-after      - matches message if it was sent after the date ARG.
                     A fully specified date looks like this:
                       \"31 Dec 1999 23:59:59 GMT\"
                     although the parts can appear in any order.
                     You can leave out any part and it will
                     default to the current date's value for that
                     part, with the exception of the hh:mm:ss
                     part which defaults to midnight.
   sent-before     - matches message if it was sent before the date ARG.
                     A fully specified date looks like this:
                       \"31 Dec 1999 23:59:59 GMT\"

                     part which defaults to midnight.
   subject         - matches message if ARG matches any part of the message's
                     subject; ARG should be a regular expression.
   text            - matches message if ARG matches any part of the text
                     portion of the message; ARG should be a
                     regular expression.
   unread          - matches message if it is old but unread.
   written         - matches message if it has been saved without its headers.
