DESCRIPTION

       The  package pop3d::dbox provides simple/basic mailbox management facilities. Each mailbox
       object manages  a  single  base  directory  whose  subdirectories  represent  the  managed
       mailboxes.  Mails in a mailbox are represented by files in a mailbox directory, where each
       of these files contains a single mail, both headers and body, in RFC 822  (http://www.rfc-
       editor.org/rfc/rfc822.txt) conformant format.

       Any mailbox object following the interface described below can be used in conjunction with
       the pop3 server core provided by the package pop3d. It is especially possible to  directly
       use  the objects created by this package in the storage callback of pop3 servers following
       the same interface as servers created by the package pop3d.

       ::pop3d::dbox::new ?dbName?
              This command creates a new database object with an associated  global  Tcl  command
              whose name is dbName.

       The  command  dbName may be used to invoke various operations on the database.  It has the
       following general form:

       dbName option ?arg arg ...?
              Option and the args determine the exact behavior of the command.

       The following commands are possible for database objects:

       dbName destroy
              Destroys the mailbox database and all transient data. The directory associated with
              the object is not destroyed.

       dbName base base
              Defines  the  base  directory containing the mailboxes to manage. If this method is
              not called none of the following methods will work.

       dbName add mbox
              Adds a mailbox of name mbox to  the  database.  The  name  must  be  a  valid  path
              component.

       dbName remove mbox
              Removes  the  mailbox specified through mbox, and the mails contained therein, from
              the database. This method will fail if the specified mailbox is locked.

       dbName move old new
              Changes the name of the mailbox old to new.

       dbName list
              Returns a list containing the names of all mailboxes in  the  directory  associated
              with the database.

       dbName exists mbox
              Returns true if the mailbox with name mbox exists in the database, or false if not.

       dbName locked mbox
              Checks if the mailbox specified through mbox is currently locked.

       dbName lock mbox
              This  method  locks  the  specified  mailbox  for use by a single connection to the
              server. This is necessary to prevent havoc  if  several  connections  to  the  same
              mailbox  are open. The complementary method is unlock. The command will return true
              if the lock could be set successfully or false if not.

       dbName unlock mbox
              This is the complementary method to lock, it revokes  the  lock  on  the  specified
              mailbox.

       dbName stat mbox
              Determines the number of messages in the specified mailbox and returns this number.
              This method fails if the mailbox mbox is not locked.

       dbName size mbox ?msgId?
              Determines the size of the message specified through its id in msgId, in bytes, and
              returns  this  number. The command will return the size of the whole maildrop if no
              message id was specified.  If specified the msgId has to be in  the  range  "1  ...
              [dbName  stat]"  or  this  call will fail. If stat was not called before this call,
              size will assume that there are zero messages in the mailbox.

       dbName dele mbox msgList
              Deletes the messages whose numeric ids  are  contained  in  the  msgList  from  the
              mailbox  specified via mbox.  The msgList must not be empty or this call will fail.
              The numeric ids in msgList have to be in the range "1 ...  [dbName stat]"  or  this
              call  will  fail.  If  stat  was not called before this call, dele will assume that
              there are zero messages in the mailbox.

       storageCmd get mbox msgId
              Returns a handle for the specified message. This handle is a mime  token  following
              the  interface  described  in the documentation of package mime. The token is read-
              only. In other words, the caller is allowed to do anything with the token except to
              modify  it.   The  msgId has to be in the range "1 ...  [dbName stat]" or this call
              will fail. If stat was not called before this call, get will assume that there  are
              zero messages in the mailbox.
