SYNOPSIS
use Mail::Box::Maildir;
my $folder = new Mail::Box::Maildir folder => $ENV{MAIL}, ...;
DESCRIPTION
This documentation describes how Maildir mailboxes work, and what you can do with the
Maildir folder object "Mail::Box::Maildir".
Maildir is not supported for Windows, because it create filenames which are not accepted
by the Windows system.

When the folder is open, some messages may be stored in the "new" sub-directory. By
default, these messages are immediately moved to the "cur" directory when the folder
is opened. Otherwise, you have to call acceptMessages() or
Mail::Box::Maildir::Message::accept().

Mail::Box::Maildir->createDirs($folderdir)
The $folderdir contains the absolute path of the location where the messages are kept.
Maildir folders contain a "tmp", "new", and "cur" sub-directory within that folder
directory as well. This method will ensure that all directories exist. Returns false
on failure.
$obj->determineBodyType($message, $head)
Inherited, see "Internals" in Mail::Box
$obj->folderIsEmpty($folderdir)
Mail::Box::Maildir->folderIsEmpty($folderdir)
Checks whether the folder whose directory is specified as absolute $folderdir is empty
or not. A folder is empty when the "tmp", "new", and "cur" subdirectories are empty
and some files which are left there by application programs. The maildir spec
explicitly states: ".qmail", "bulletintime", "bulletinlock" and "seriallock". If any
other files are found, the directory is considered not-empty.

How MAILDIR folders work
Maildir-type folders use a directory to store the messages of one folder. Each message is
stored in a separate file. This seems useful, because changes in a folder change only a
few of these small files, in contrast with file-based folders where changes in a folder
cause rewrites of huge folder-files.
However, Maildir based folders perform very bad if you need header information of all
messages. For instance, if you want to have full knowledge about all message-threads (see
Mail::Box::Thread::Manager) in the folder, it requires to read all header lines in all
message files. And usually, reading your messages as threads is desired. Maildir
maintains a tiny amount of info visible in the filename, which may make it perform just a
little bit faster than MH.
DIAGNOSTICS
Error: Cannot append Maildir message in $new to folder $self.
The message (or messages) could not be stored in the right directories for the Maildir
folder.
Error: Cannot create Maildir directory $dir: $!
A Maildir folder is represented by a directory, with some sub-directories. The top
folder directory could not be created for the reason indicated.
Error: Cannot create Maildir folder $name.
One or more of the directories required to administer a Maildir folder could not be
created.
Error: Cannot create Maildir message file $new.
A message is converted from some other message format into a Maildir format by writing
it to a file with a name which contains the status flags of the message. Apparently,
creating this file failed.
Error: Cannot create Maildir subdir $dir: $!
Each Maildir folder has three sub-directories for administration: "new", "tmp", and
"cur". The mentioned directory could not be created for the indicated reason.
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
controled 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 $name not deleted: not writable.
The folder must be opened with write access via new(access), otherwise removing it
will be refused. So, you may have write-access according to the operating system, but
that will not automatically mean that this "delete" method permits you to. The
reverse remark is valid as well.
Error: Invalid timespan '$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.
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.
