80             have to call acceptMessages() or

241           The $folderdir contains the absolute path of the location where the
242           messages are kept.  Maildir folders contain a "tmp", "new", and
243           "cur" sub-directory within that folder directory as well.  This
244           method will ensure that all directories exist.  Returns false on
245           failure.

251       Mail::Box::Maildir->folderIsEmpty($folderdir)
252           Checks whether the folder whose directory is specified as absolute
253           $folderdir is empty or not.  A folder is empty when the "tmp",
254           "new", and "cur" subdirectories are empty and some files which are
255           left there by application programs.  The maildir spec explicitly
256           states: ".qmail", "bulletintime", "bulletinlock" and "seriallock".
257           If any other files are found, the directory is considered not-
258           empty.

371   How MAILDIR folders work
372       Maildir-type folders use a directory to store the messages of one
373       folder.  Each message is stored in a separate file.  This seems useful,
374       because changes in a folder change only a few of these small files, in
375       contrast with file-based folders where changes in a folder cause
376       rewrites of huge folder-files.
377
378       However, Maildir based folders perform very bad if you need header
379       information of all messages.  For instance, if you want to have full
380       knowledge about all message-threads (see Mail::Box::Thread::Manager) in
381       the folder, it requires to read all header lines in all message files.
382       And usually, reading your messages as threads is desired.  Maildir
383       maintains a tiny amount of info visible in the filename, which may make
384       it perform just a little bit faster than MH.

DIAGNOSTICS

387       Error: Cannot append Maildir message in $new to folder $self.
388           The message (or messages) could not be stored in the right
389           directories for the Maildir folder.
390
391       Error: Cannot create Maildir directory $dir: $!
392           A Maildir folder is represented by a directory, with some sub-
393           directories.  The top folder directory could not be created for the
394           reason indicated.
395
396       Error: Cannot create Maildir folder $name.
397           One or more of the directories required to administer a Maildir
398           folder could not be created.
399
400       Error: Cannot create Maildir message file $new.
401           A message is converted from some other message format into a
402           Maildir format by writing it to a file with a name which contains
403           the status flags of the message.  Apparently, creating this file
404           failed.

406       Error: Cannot create Maildir subdir $dir: $!
407           Each Maildir folder has three sub-directories for administration:
408           "new", "tmp", and "cur".  The mentioned directory could not be
409           created for the indicated reason.
410
411       Warning: Changes not written to read-only folder $self.
412           You have opened the folder read-only --which is the default set by
413           new(access)--, made modifications, and now want to close it.  Set
414           close(force) if you want to overrule the access mode, or close the
415           folder with close(write) set to "NEVER".
416
417       Error: Copying failed for one message.
418           For some reason, for instance disc full, removed by external
419           process, or read-protection, it is impossible to copy one of the
420           messages.  Copying will proceed for the other messages.
421
422       Error: Destination folder $name is not writable.
423           The folder where the messages are copied to is not opened with
424           write access (see new(access)).  This has no relation with write
425           permission to the folder which is controlled by your operating
426           system.
427
428       Warning: Different messages with id $msgid
429           The message id is discovered more than once within the same folder,
430           but the content of the message seems to be different.  This should
431           not be possible: each message must be unique.
432
433       Error: Folder $name is opened read-only
434           You can not write to this folder unless you have opened the folder
435           to write or append with new(access), or the "force" option is set
436           true.
437
438       Error: Folder $name not deleted: not writable.
439           The folder must be opened with write access via new(access),
440           otherwise removing it will be refused.  So, you may have write-
441           access according to the operating system, but that will not
442           automatically mean that this "delete" method permits you to.  The
443           reverse remark is valid as well.
444
445       Error: Invalid timespan '$timespan' specified.
446           The string does not follow the strict rules of the time span syntax
447           which is permitted as parameter.
448
449       Warning: Message-id '$msgid' does not contain a domain.
450           According to the RFCs, message-ids need to contain a unique random
451           part, then an "@", and then a domain name.  This is made to avoid
452           the creation of two messages with the same id.  The warning emerges
453           when the "@" is missing from the string.
454
455       Error: Package $package does not implement $method.
456           Fatal error: the specific package (or one of its superclasses) does
457           not implement this method where it should. This message means that
458           some other related classes do implement this method however the
459           class at hand does not.  Probably you should investigate this and
460           probably inform the author of the package.
461
462       Error: Unable to create subfolder $name of $folder.
463           The copy includes the subfolders, but for some reason it was not
464           possible to copy one of these.  Copying will proceed for all other
465           sub-folders.
466
467       Error: Writing folder $name failed
468           For some reason (you probably got more error messages about this
469           problem) it is impossible to write the folder, although you should
470           because there were changes made.
