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!

       $obj->from( [<$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.

           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.

           software => STRING
           type => STRING
           version => STRING

   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()

   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.

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()
