The message

$obj->container See The message in Mail::Message

$obj->copyTo(FOLDER, OPTIONS) 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->guessTimestamp The filename of a CWMail::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.

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. CWundef is returned when the rename is required but fails.

Internals

$obj->accept([BOOLEAN]) Accept a message for the folder. This will move it from the CWnew or CWtmp sub-directories into the CWcur sub-directory (or back when the BOOLEAN is CWfalse). When you accept an already accepted message, nothing will happen.

DIAGNOSTICS

Error: Cannot create parser for CW$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 CW$include.

Unknown alternative for the forward(include). Valid choices are CWNO, CWINLINE, CWATTACH, and CWENCAPSULATE.

Error: Cannot include reply source as CW$include.

Unknown alternative for the CWinclude option of reply(). Valid choices are CWNO, CWINLINE, and CWATTACH.

Error: Cannot write message to CW$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 CW$new to CW$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: 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 CWvia options.

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 CW$package does not implement CW$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: 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: forwardAttach requires a preamble object

Error: forwardEncapsulate requires a preamble object

Error: no rebuild rule CW$name defined.

DETAILS

Labels

Flags in filename

When new messages arrive on system and have to be stored in a maildir folder, they are put in the CWnew sub-directory of the folder (first created in the CWtmp sub-directory and then immediately moved to CWnew). 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 CW1014220791.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 CWnew which are new arival, and messages in CWcur. The latter are labeled CWaccepted. To move a message from CWnew to CWcur, 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 CW':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.
