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
 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!

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

METHODS

$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.

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

    %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.

    Bcc => STRING|OBJECT|OBJECTS
    Cc => STRING|OBJECT|OBJECTS
    Date => STRING
        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 => STRING|FIELD
    From => STRING|OBJECT|OBJECTS
    Message-ID => STRING|FIELD
        The "Resent-Message-ID" which identifies this resent group. The FIELD must contain a message id.

    Received => STRING
        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 => STRING|FIELD
    Sender => STRING|OBJECT
        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 => STRING|OBJECT|OBJECTS
    head => OBJECT
        The header where the data is stored in. By default a Mail::Message::Head::Partial is created for you.

    log => LEVEL
    message_head => HEAD
        The real header 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.

    software => STRING
    trace => LEVEL
    type => STRING
    version => STRING

  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().

$obj->addFields( [$fieldnames] )
    Not applicable to resent-groups: the same name can appear in more than one group. Therefore, a FIELDNAME is sufficiently distinctive.

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

     $msg->bounce(To => 'fish@tux.aq')->send;   # the same

     my $this = 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.

$obj->isResentGroupFieldName($name)
Mail::Message::Head::ResentGroup->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.

$obj->detected($type, $software, $version)

DIAGNOSTICS

Error: Message header required for creation of ResentGroup.
    It is required to know to which header the resent-group is created. Use the "head" option. Maybe you should use Mail::Message::Head::Complete::addResentGroup() with DATA, which will organize the correct initiations for you.

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.
