DESCRIPTION

Extends "DESCRIPTION" in Mail::Box::Message.

METHODS
Extends "METHODS" in Mail::Box::Message.

  Constructors
Extends "Constructors" in Mail::Box::Message.

$obj->clone(%options)
    Inherited, see "Constructors" in Mail::Message

$class->new(%options)
    Messages in file-based folders use the following options for creation: Improves base, see "Constructors" in Mail::Reporter

     -Option    --Defined in        --Default
      body        Mail::Message       undef

    body => $object
    body_type => CODE|$class
    deleted => BOOLEAN
    field_type => $class
    folder => $folder
    from_line => $line
        The $line which begins each message in the file. Some people detest this line, but this is just how things were invented...

    head => $object
    head_type => $class
    labels => \@pairs|\%settings

  Attributes
Extends "Attributes" in Mail::Box::Message.

$obj->folder( [$folder] )
    Inherited, see "Attributes" in Mail::Box::Message

$obj->fromLine( [$line] )
    Many people detest file-style folders because they store messages all in one file, where a line starting with "From " leads the header. If we receive a message from a file-based folder, we store that line. If we write to such a file, but there is no such line stored, then we try to generate one.

    If $line is provided, then the starting line is set to this value.

$obj->escapedBody()
    Mbox folders contain multiple messages in one file, using a separator line to keep them apart. Typically, these lines start with "From ". Lines within the message could interfere with this separator, and should therefore be translated.

    This method will return the escaped text of the body as reference.

$obj->write( [$fh] )
    Write one message to a file handle. It is the message including the leading 'From ' line and trailing blank. The From-line may interfere with lines in the body: those lines are escaped with an extra '>'. Improves base, see "The message" in Mail::Message

    » example:

      $msg->write(\*FILE);    # print the message with encaps to FILE
      $msg->write;            # message with encaps to selected filehandle
      $msg->print(\*FILE);    # the message without encaps.

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: Unable to read delayed body.
    Cast by loadBody()

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()

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()

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.
