SYNOPSIS

18        # Do not instantiate this object
19

DESCRIPTION

21       This documentation describes the way directory organized mailboxes
22       work.  At the moment, this object is extended by
23
24       •   Mail::Box::MH
25
26           MH folders, which are represented by a directory containing files
27           which are sequentially numbered.
28
29       •   Mail::Box::Maildir
30
31           Maildir folders, which are located in a directory which has sub-
32           directories named "tmp", "new", and "cur".  Each of these
33           directories may contain files with names which are a combination of
34           a numeric timestamp and some status flags.
35
36       •   Mail::Box::Netzwert
37
38           This folder type was especially developed for Netzwert AG,
39           optimized to run on a cluster of servers with folders on NFS.  The
40           code is not publicly available (yet).
41

DIAGNOSTICS

360       Warning: Changes not written to read-only folder $self.
361           You have opened the folder read-only --which is the default set by
362           new(access)--, made modifications, and now want to close it.  Set
363           close(force) if you want to overrule the access mode, or close the
364           folder with close(write) set to "NEVER".
365
366       Error: Copying failed for one message.
367           For some reason, for instance disc full, removed by external
368           process, or read-protection, it is impossible to copy one of the
369           messages.  Copying will proceed for the other messages.
370
371       Error: Destination folder $name is not writable.
372           The folder where the messages are copied to is not opened with
373           write access (see new(access)).  This has no relation with write
374           permission to the folder which is controlled by your operating
375           system.
376
377       Warning: Different messages with id $msgid
378           The message id is discovered more than once within the same folder,
379           but the content of the message seems to be different.  This should
380           not be possible: each message must be unique.
381
382       Error: Folder $name is opened read-only
383           You can not write to this folder unless you have opened the folder
384           to write or append with new(access), or the "force" option is set
385           true.
386
387       Error: Folder $name not deleted: not writable.
388           The folder must be opened with write access via new(access),
389           otherwise removing it will be refused.  So, you may have write-
390           access according to the operating system, but that will not
391           automatically mean that this "delete" method permits you to.  The
392           reverse remark is valid as well.
393
394       Warning: Folder directory $directory is write-protected.
395           The folder directory does already exist and is write protected,
396           which may interfere with the requested write access.  Change
397           new(access) or the permissions on the directory.
398
399       Error: Invalid timespan '$timespan' specified.
400           The string does not follow the strict rules of the time span syntax
401           which is permitted as parameter.
402
403       Warning: Message-id '$msgid' does not contain a domain.
404           According to the RFCs, message-ids need to contain a unique random
405           part, then an "@", and then a domain name.  This is made to avoid
406           the creation of two messages with the same id.  The warning emerges
407           when the "@" is missing from the string.
408
409       Warning: No directory $name for folder of $class
410       Error: Package $package does not implement $method.
411           Fatal error: the specific package (or one of its superclasses) does
412           not implement this method where it should. This message means that
413           some other related classes do implement this method however the
414           class at hand does not.  Probably you should investigate this and
415           probably inform the author of the package.

417       Error: Unable to create subfolder $name of $folder.
418           The copy includes the subfolders, but for some reason it was not
419           possible to copy one of these.  Copying will proceed for all other
420           sub-folders.
421
422       Error: Writing folder $name failed
423           For some reason (you probably got more error messages about this
424           problem) it is impossible to write the folder, although you should
425           because there were changes made.
