DESCRIPTION

       The package pop3d::dbox provides simple/basic mailbox management facilities. Each mailbox object manages a single base directory whose sub-
       directories 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 speci-
	      fied 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.
