DESCRIPTION
The package pop3d::dbox provides simple/basic mailbox management facil-
ities. Each mailbox object manages a single base directory whose subdi-
rectories represent the managed mailboxes. Mails in a mailbox are rep-
resented 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 direc-
tory 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 con-
tained 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 data-
base, 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 con-
nection to the server. This is necessary to prevent havoc if
several connections to the same mailbox are open. The complemen-
tary 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 spec-
ified. 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 documenta-
tion 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.
