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


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 the Mail::Message::Head::FieldGroup manpage

$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.

 Option        Defined in       Default                
 Bcc                            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 the Mail::Message::Head::FieldGroup manpage

$obj->delete

See The header in the Mail::Message::Head::FieldGroup manpage

$obj->fieldNames

See The header in the Mail::Message::Head::FieldGroup manpage

$obj->fields

See The header in the Mail::Message::Head::FieldGroup manpage

$obj->head

See The header in the Mail::Message::Head::FieldGroup manpage

$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 the Mail::Message::Head::FieldGroup manpage

$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 the Mail::Message::Head::FieldGroup manpage

$obj->version

See Access to the header in the Mail::Message::Head::FieldGroup manpage

Internals

$obj->collectFields([NAME])

See Internals in the Mail::Message::Head::FieldGroup manpage

$obj->createReceived([DOMAIN])

Create a recieved 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.
