Labels

Predefined labels
Extends "Predefined labels" in Mail::Box::Dir::Message.
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 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
