   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

•   Mail::Box::MH

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

•   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.

•   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).

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.
