NAME
Mail::Message::Head::ResentGroup - header fields tracking message delivery

INHERITANCE
 Mail::Message::Head::ResentGroup
   is a Mail::Message::Head::FieldGroup
   is a Mail::Reporter

SYNOPSIS
  use Mail::Message::Head::ResentGroup;
  my $rg = Mail::Message::Head::ResentGroup->new(head => $head,
               From => 'me@home.nl', To => 'You@tux.aq');
  $head->addResentGroup($rg);

  my $rg = $head->addResentGroup(From => 'me');

  my @from = $rg->From;

  my @rgs = $head->resentGroups;
  $rg[2]->delete if @rgs > 2;

DESCRIPTION
A resent group is a set of header fields which describe one intermediate step in the message transport. Resent groups have NOTHING to do with user activety; there is no relation to the "user's" sense of creating reply, forward, or bounce messages at all!

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

$obj->from( [<$head|$message>, %options] )
    WARNING: this method has two very different purposes. For backward compatibility reasons, without arguments resentFrom() is called to return the "From" field of this resent group.

    With any arguments, a list of "Mail::Message::Head::ResentGroup" objects is returned, taken from the specified $message or message $head. Improves base, see "Constructors" in Mail::Message::Head::FieldGroup

$any->implementedTypes()
    Inherited, see "Constructors" in Mail::Message::Head::FieldGroup

$class->new( [@fields], %options )
    Create an object which maintains one set of resent headers. The @fields are Mail::Message::Field objects from the same header.

    All %options which start with capitals will be used to construct additional fields. These option names are prepended with "Resent-*", keeping the capitization of what is specified. Improves base, see "Constructors" in Mail::Message::Head::FieldGroup

    Bcc => $text|$field|\@fields
    Cc => $text|$field|\@fields
    Date => $date
        When this resent-group is dispatched by the resender of the message. Like the "Date" field, it is not the date and time that the message was actually transported.

    Delivered-To => $text|$field
    From => $text|$field|\@fields
    Message-ID => $text|$field
        The "Resent-Message-ID" which identifies this resent group. The $field must contain a message id.

    Received => $text
        The "Received" field is the starting line for a resent group of header lines. If it is not defined, one is created using createReceived().

    Return-Path => $text|$field
    Sender => $text|$field
        Only permitted when more than one from address is specified. In this case, it selects one of these addresses as the main originator of the message.

    To => $text|$field|\@fields
    head => $head
        The $head object where the data is stored in. By default a Mail::Message::Head::Partial is created for you.

    message_head => $head
        The real $head of the message where this resent group is part of. The "head" used in this class is only a container for a subset of fields.

  Attributes
Extends "Attributes" in Mail::Message::Head::FieldGroup.

  The header
Extends "The header" in Mail::Message::Head::FieldGroup.

$obj->add( <$field, $value> | $object )
    All fields appear only once, so add() behaves as set(). Improves base, see "The header" in Mail::Message::Head::FieldGroup

$obj->addFields( [$fieldnames] )
    Not applicable to resent-groups: the same name can appear in more than one group. Therefore, a FIELDNAME is sufficiently distinctive. Improves base, see "The header" in Mail::Message::Head::FieldGroup

$obj->attach($head)
    Inherited, see "The header" in Mail::Message::Head::FieldGroup

$obj->delete()
    Inherited, see "The header" in Mail::Message::Head::FieldGroup

$obj->fieldNames()
    Inherited, see "The header" in Mail::Message::Head::FieldGroup

$obj->fields()
    Inherited, see "The header" in Mail::Message::Head::FieldGroup

$obj->head()
    Inherited, see "The header" in Mail::Message::Head::FieldGroup

$obj->messageHead( [$head] )
    Returns (optionally after setting) the real header where this resent group belongs to. This may be "undef" at creation, and then later filled in when Mail::Message::Head::Complete::addResentGroup() is called.

$obj->orderedFields()
    Returns the fields in the order as should appear in header according to rfc2822. For the "Resent-*" fields of the group, the order is not that important, but the "Return-Path", "Delivered-To", and "Received" must come first. Only fields mentioned in the RFC are returned.

$obj->set( <$field, $value> | $object )
    Set a $field to a (new) $value. The $field names which do not start with 'Resent-*' but need it will have that added. It is also an option to specify a fully prepared message field $object. In any case, a field $object is returned.

    » example:

      my $rg = Mail::Message::Head::ResentGroup->new;
      $rg->set(To => 'fish@tux.aq');
      $msg->addResentGroup($rg);
      $msg->send;

      $msg->bounce(To => 'fish@tux.aq')->send;   # the same
      my $rg = Mail::Message::Head::ResentGroup->new(To => 'fish@tux.aq');

  Access to the header
Extends "Access to the header" in Mail::Message::Head::FieldGroup.

$obj->bcc()
    In scalar context, the "Resent-Bcc" field is returned. In list context, the addresses as specified within the bcc field are returned as Mail::Address objects. Bcc fields are not transmitted (hidden for external parties).

$obj->cc()
    In scalar context, the "Resent-Cc" field is returned. In list context, the addresses as specified within the cc field are returned as Mail::Address objects.

$obj->date()
    Returns the "Resent-Date" field, or "undef" if it was not defined.

$obj->dateTimestamp()
    The timestamp as stored within the "Resent-Date" field converted to local system time.

$obj->deliveredTo()
    The field which describes the "Delivered-To" of this resent group.

$obj->destinations()
    Returns a list of all addresses specified in the "Resent-To", "-Cc", and "-Bcc" fields of this resent group.

$any->isResentGroupFieldName($name)

$obj->messageId()
    Returns the message-ID used for this group of resent lines.

$obj->received()
    The field which describes the "Received" data of this resent group.

$obj->receivedTimestamp()
    The timestamp as stored within the "Received" field converted to local system time.

$obj->resentFrom()
    In scalar context, the "Resent-From" field is returned. In list context, the addresses as specified within the from field are returned as Mail::Address objects.

    For reasons of backward compatibility and consistency, the from() method will return the same as this method.

$obj->returnPath()
    The field which describes the "Return-Path" of this resent group.

$obj->sender()
    In scalar context, the "Resent-Sender" field is returned. In list context, the addresses as specified within the from field are returned as Mail::Address objects.

$obj->software()
    Inherited, see "Access to the header" in Mail::Message::Head::FieldGroup

$obj->to()
    In scalar context, the "Resent-To" field is returned. In list context, the addresses as specified within the to field are returned as Mail::Address objects.

$obj->type()
    Inherited, see "Access to the header" in Mail::Message::Head::FieldGroup

$obj->version()
    Inherited, see "Access to the header" in Mail::Message::Head::FieldGroup

  Internals
Extends "Internals" in Mail::Message::Head::FieldGroup.

$obj->collectFields( [$name] )
    Inherited, see "Internals" in Mail::Message::Head::FieldGroup

$obj->createReceived( [$domain] )
    Create a received field for this resent group. This is automatically called if none was specified during creation of this resent group object.

    The content of this field is described in RFC2821 section 4.4. It could use some improvement.

    Inherited, see "Internals" in Mail::Message::Head::FieldGroup

DIAGNOSTICS

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()
