Predefined labels

Status and X-Status fields

Extends "Status and X-Status fields" in Mail::Box::Dir::Message.

The .mh_sequences file

Typically, the file which contains the labels is called ".mh_sequences". The MH messages are numbered from 1. As example content for ".mh_sequences":

  cur: 93
  unseen: 32 35-56 67-80

To generalize labels on messages, two are treated specially:

cur
The "cur" specifies the number of the message where the user stopped reading mail from this folder at last access. Internally in these modules referred to as label "current".
unseen
With "unseen" is listed which message was never read. This must be a mistake in the design of MH: it must be a source of confusion. People should never use labels with a negation in the name:
```
  if($seen)           if(!$unseen)    #yuk!
  if(!$seen)          if($unseen)
  unless($seen)       unless($unseen) #yuk!
    
```
So: label "unseen" is translated into "seen" for internal use.

DIAGNOSTICS

Error: Cannot include forward source as $kind.: Unknown alternative for the forward(include). Valid choices are "NO", "INLINE", "ATTACH", and "ENCAPSULATE". Cast by forward()
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. Cast by send()
Error: cannot coerce a $type object into a $me object.: Cast by coerce()
Error: cannot include reply source as $kind.: Unknown alternative for the "include" option of reply(). Valid choices are "NO", "INLINE", and "ATTACH". Cast by reply()
Error: cannot read message from a $source}.: Cast by read()
Fault: cannot write message to $file: $!: 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. Cast by create()
Error: class $package does not implement method $method.: Fatal error: the specific $package (or one of its superclasses) does not implement this method where it should. This message means that some other related classes do implement this method however the class at hand does not. Probably you should investigate this and probably inform the author of the package. Cast by notImplemented()
Error: coercion starts with some object, not '$type'.: Cast by coerce()
Fault: failed to rename file $from to $to: $!: 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. Cast by create()
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(). Cast by bounce()
Error: method forwardAttach requires a preamble.: Cast by forwardAttach()
Error: method forwardEncapsulate requires a preamble.: Cast by forwardEncapsulate()
Error: method forwardNo requires a To.: Cast by forwardNo()
Error: method forwardNo requires a body.: Cast by forwardNo()
Error: no rebuild rule $name defined.: Cast by rebuild()
Error: only build() Mail::Message's; they are not in a folder yet.: You may wish to construct a message to be stored in a some kind of folder, but you need to do that in two steps. First, create a normal Mail::Message, and then add it to the folder. During this Mail::Box::addMessage() process, the message will get coerce()-d into the right message type, adding storage information and the like. Cast by build()
Error: please install Email::Simple.: Cast by coerce()
Error: please install MIME::Entity.: Cast by coerce()
Error: please install Mail::Internet.: Cast by coerce()
Error: select parts via '$what'?: Cast by parts()
Warning: skipped unknown key '$key' in build.: Cast by build()
Error: unable to read delayed body for message $msgid.: 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. Cast by loadBody()
Error: unable to read delayed head for message $msgid.: 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. Cast by loadBody()
