Mail::Box::Dir(3pm)   User Contributed Perl Documentation  Mail::Box::Dir(3pm)

NAME
       Mail::Box::Dir - handle folders with a file per message.

INHERITANCE
        Mail::Box::Dir
          is a Mail::Box
          is a Mail::Reporter

        Mail::Box::Dir is extended by
          Mail::Box::MH
          Mail::Box::Maildir

SYNOPSIS
        # Do not instantiate this object

DESCRIPTION
       This documentation describes the way directory organized mailboxes
       work.  At the moment, this object is extended by

       o   Mail::Box::MH

           MH folders, which are represented by a directory containing files
           which are sequentially numbered.

       o   Mail::Box::Maildir

           Maildir folders, which are located in a directory which has sub-
           directories named "tmp", "new", and "cur".  Each of these
           directories may contain files with names which are a combination of
           a numeric timestamp and some status flags.

       o   Mail::Box::Netzwert

           This folder type was especially developed for Netzwert AG,
           optimized to run on a cluster of servers with folders on NFS.  The
           code is not publicly available (yet).

       Extends "DESCRIPTION" in Mail::Box.

OVERLOADED
       Extends "OVERLOADED" in Mail::Box.

DIAGNOSTICS
       Warning: Changes not written to read-only folder $self.
           You have opened the folder read-only --which is the default set by
           new(access)--, made modifications, and now want to close it.  Set
           close(force) if you want to overrule the access mode, or close the
           folder with close(write) set to "NEVER".

       Error: Copying failed for one message.
           For some reason, for instance disc full, removed by external
           process, or read-protection, it is impossible to copy one of the
           messages.  Copying will proceed for the other messages.

       Error: Destination folder $name is not writable.
           The folder where the messages are copied to is not opened with
           write access (see new(access)).  This has no relation with write
           permission to the folder which is controlled by your operating
           system.

       Warning: Different messages with id $msgid
           The message id is discovered more than once within the same folder,
           but the content of the message seems to be different.  This should
           not be possible: each message must be unique.

       Error: Folder $name is opened read-only
           You can not write to this folder unless you have opened the folder
           to write or append with new(access), or the "force" option is set
           true.

       Error: Folder $name not deleted: not writable.
           The folder must be opened with write access via new(access),
           otherwise removing it will be refused.  So, you may have write-
           access according to the operating system, but that will not
           automatically mean that this "delete" method permits you to.  The
           reverse remark is valid as well.

       Warning: Folder directory $directory is write-protected.
           The folder directory does already exist and is write protected,
           which may interfere with the requested write access.  Change
           new(access) or the permissions on the directory.

       Error: Invalid timespan '$timespan' specified.
           The string does not follow the strict rules of the time span syntax
           which is permitted as parameter.

       Warning: Message-id '$msgid' does not contain a domain.
           According to the RFCs, message-ids need to contain a unique random
           part, then an "@", and then a domain name.  This is made to avoid
           the creation of two messages with the same id.  The warning emerges
           when the "@" is missing from the string.

       Warning: No directory $name for folder of $class
       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does
           not implement this method where it should. This message means that
           some other related classes do implement this method however the
           class at hand does not.  Probably you should investigate this and
           probably inform the author of the package.

       Error: Unable to create subfolder $name of $folder.
           The copy includes the subfolders, but for some reason it was not
           possible to copy one of these.  Copying will proceed for all other
           sub-folders.

       Error: Writing folder $name failed
           For some reason (you probably got more error messages about this
           problem) it is impossible to write the folder, although you should
           because there were changes made.
