WARNING: This sequence number has nothing to do with the message's filename, which in case of MH folders are also numbers! If you need that one, use the File::Basename subroutine basename of the filename.

DETAILS
Structure of a Message
The header
The body
Message object implementation
Message class implementation
Labels
Predefined labels
Status and X-Status fields
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 labelcurrent
.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 intoseen
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
, andENCAPSULATE
. - Error: Cannot include reply source as $include.
-
Unknown alternative for the
include
option of reply(). Valid choices areNO
,INLINE
, andATTACH
. - 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
