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!

METHODS

Constructors

$obj->clone
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->implementedTypes

See ``Constructors'' in Mail::Message::Head::FieldGroup

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.
  Option      --Defined in     --Default
  Bcc                            undef
  Cc                             undef

. 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. Be dafault 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

$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)

See ``The header'' in Mail::Message::Head::FieldGroup

$obj->delete

See ``The header'' in Mail::Message::Head::FieldGroup

$obj->fieldNames

See ``The header'' in Mail::Message::Head::FieldGroup

$obj->fields

See ``The header'' in Mail::Message::Head::FieldGroup

$obj->head

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

$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

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

See ``Access to the header'' in Mail::Message::Head::FieldGroup

$obj->version

See ``Access to the header'' in Mail::Message::Head::FieldGroup

Internals

$obj->collectFields([NAME])
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.
