The message

Extends ``The message'' in Mail::Box::Dir::Message.

$obj->container(): Inherited, see ``The message'' in Mail::Message
$obj->copyTo($folder, %options): Inherited, see ``The message'' in Mail::Box::Message
$obj->filename( [$filename] ): Returns the current filename for this message. If the $filename argument is specified, a new filename will be set. For maildir messages this means that modifications are immediately performed: there will be a rename (move) from the old name to the new name. Labels may change within in the message object as well.
$obj->folder( [$folder] ): Inherited, see ``The message'' in Mail::Box::Message
$obj->isDummy(): Inherited, see ``The message'' in Mail::Message

The header

Extends ``The header'' in Mail::Box::Dir::Message.

$obj->from(): Inherited, see ``The header'' in Mail::Message
$obj->get($fieldname): Inherited, see ``The header'' in Mail::Message
$obj->guessTimestamp(): The filename of a "Mail::Box::Maildir::Message" contains a timestamp. This is a wild guess about the actual time of sending of the message: it is the time of receipt which may be seconds to hours off. But is still a good guess... When the message header is not parsed, then this date is used.
$obj->head( [$head] ): Inherited, see ``The header'' in Mail::Message
$obj->nrLines(): Inherited, see ``The header'' in Mail::Message

Labels

$obj->labelsToFilename(): When the labels on a message change, this may implicate a change in the message's filename. The change will take place immediately. The new filename (which may be the same as the old filename) is returned. "undef" is returned when the rename is required but fails.

Flags in filename

When new messages arrive on system and have to be stored in a maildir folder, they are put in the "new" sub-directory of the folder (first created in the "tmp" sub-directory and then immediately moved to "new"). The following information was found at <http://cr.yp.to/proto/maildir.html>.

Each message is written in a separate file. The filename is constructed from the time-of-arrival, a hostname, an unique component, a syntax marker, and flags. For example "1014220791.meteor.42:2,DF". The filename must match:

 my ($time, $unique, $hostname, $info)
    = $filename =~ m!^(\d+)\.(.*)\.(\w+)(\:.*)?$!;
 my ($semantics, $flags)
    = $info =~ m!([12])\,([DFPRST]*)$!;
 my @flags = split //, $flags;

When an application opens the folder, there may be messages in "new" which are new arival, and messages in "cur". The latter are labeled "accepted". To move a message from "new" to "cur", you have two options with the same effect:

  $msg->accept;
  $msg->label(accept => 1);

See accept(), label(), Mail::Box::Maildir::new(accept_new), and Mail::Box::Maildir::acceptMessages()

The messages are moved, and their name is immediately extended with flags. An example:

 new/897979431.meteor.42      may become
 cur/897979431.meteor.42:2,FS

The added characters ':2,' refer to the ``second state of processing'', where the message has been inspected. And the characters (which should be in alphabetic order) mean

 D      => draft
 F      => flagged
 R      => replied  (answered)
 S      => seen
 T      => deleted  (tagged for deletion)

Some maildir clients support
P => passed (resent/forwarded/bounced to someone else)

The flags will immediately change when label() or delete() is used, which differs from other message implementations: maildir is stateless, and should not break when applications crash.

DIAGNOSTICS

Error: Cannot coerce a $class object into a $class object
Error: Cannot create parser for $filename.: For some reason (the previous message have told you already) it was not possible to create a message parser for the specified filename.
Error: Cannot include forward source as $include.: Unknown alternative for the forward(include). Valid choices are "NO", "INLINE", "ATTACH", and "ENCAPSULATE".
Error: Cannot include reply source as $include.: Unknown alternative for the "include" option of reply(). Valid choices are "NO", "INLINE", and "ATTACH".
Error: Cannot write message to $filename: $!: When a modified or new message is written to disk, it is first written to a temporary file in the folder directory. For some reason, it is impossible to create this file.
Error: Failed to move $new to $filename: $!: When a modified or new message is written to disk, it is first written to a temporary file in the folder directory. Then, the new file is moved to replace the existing file. Apparently, the latter fails.
Error: Method bounce requires To, Cc, or Bcc: The message bounce() method forwards a received message off to someone else without modification; you must specified it's new destination. If you have the urge not to specify any destination, you probably are looking for reply(). When you wish to modify the content, use forward().
Error: Method forwardAttach requires a preamble
Error: Method forwardEncapsulate requires a preamble
Error: No address to create forwarded to.: If a forward message is created, a destination address must be specified.
Error: No default mailer found to send message.: The message send() mechanism had not enough information to automatically find a mail transfer agent to sent this message. Specify a mailer explicitly using the "via" options.
Error: No rebuild rule $name defined.
Error: Only build() Mail::Message's; they are not in a folder yet: You may wish to construct a message to be stored in a some kind of folder, but you need to do that in two steps. First, create a normal Mail::Message, and then add it to the folder. During this Mail::Box::addMessage() process, the message will get coerce()-d into the right message type, adding storage information and the like.
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 read delayed body.: For some reason, the header of the message could be read, but the body cannot. Probably the file has disappeared or the permissions were changed during the progress of the program.
Error: Unable to read delayed head.: Mail::Box tries to be lazy with respect to parsing messages. When a directory organized folder is opened, only the filenames of messages are collected. At first use, the messages are read from their file. Apperently, a message is used for the first time here, but has disappeared or is unreadible for some other reason.
Error: coercion starts with some object
