NAME

Mail::Header::Generator - Generate various email headers.

VERSION

Version 0.200

SYNOPSIS


            

              
              
   use Mail::Header::Generator ();
   my $gen = Mail::Header::Generator->new({
hostname      => 'foobar.example.com',
   });
   # Generate Message-Id: header contents.  $message_id will
   # contain:
   #    <20100601142143.GA9035@foobar.example.com>
   # and use the hostname provided to the constructor.
   my $message_id = $gen->message_id({
       timestamp => time(),
queue_id  => 'GA9035',
   });
   # Generate a Received: header, including the Received: name.
   # Will result in something similar to:
   #   Received: from localhost.localdomain ([127.0.0.1] localhost)
   #    by foobar.example.com with ESMTP id o53JaiwX007246; Thu, 03 Jun 2010 15:37:51 -0400
   my $received   = $gen->received({
header_name    => undef,
relay_address  => '127.0.0.1',
relay_hostname => 'localhost',
helo           => 'localhost.localdomain',
protocol       => 'ESMTP',
queue_id       => 'o53JaiwX007246',
   });

DESCRIPTION

This class generates RFC 5321/5322-compliant headers for use in email messages.

METHODS

Class Methods

new ( { args } )

Constructs a new Mail::Header::Generator.

Takes a hash reference containing default arguments to be used for the various header-generation callbacks.

Commonly useful keys for default arguments are:

timestamp

A UNIX timestamp (from time()).

hostname

The local host name.

queue_id

The queue ID for the message you're generating these headers for.

Common Parameters

The following methods all take named parameters (as a hash reference). The following parameters are common:

header_name

The name of this header. If this key exists and has a value of undef, the contents of the generated header will be returned with no name prefixed. If the key exists, and has a value, that value will be used as the name. If the key does not exist, the header will default to the same name as the method used to create it.

timestamp

UNIX timestamp (as generated by time()) for this header. If not provided, defaults to the current value of time().

hostname

The local host name.

Instance Methods

message_id ( ... )

Returns a string containing a Message-ID header.

Takes a hash reference containing values to use in generating this header. Valid keys are:

header_name

Defaults to 'Message-ID' if not provided.

timestamp
hostname

See top of this section for further details on these parameters.

received ( ... )

Returns a string containing a Received header.

Takes a hash reference containing values to use in generating this header. Valid keys are:

header_name

Defaults to 'Received' if not provided.

timestamp
hostname
product_name

String containing name of product responsible for adding this header. Will be added as a comment in the generated header if present.

protocol

Protocol this message was received over. Should be "SMTP" or "ESMTP" for standards compliance. Will not be used in the generated header if not provided.

recipients

An array reference of recipient addresses. Currently, a 'for' tag will be created as part of the header only if the recipients array contains a single address.

relay_address

String representation of IPv4 or IPv6 address that relayed this message to us. If not present, no 'from' section of the header will be created.

relay_hostname

Hostname of relay address.

sender

The envelope sender address. If present, an 'envelope-sender' comment will be added to the generated header.

user

Local user that generated this message. Defaults to $ENV{USER} if not present and no relay address was provided.

See top of this section for further details on these parameters.

rfc2822_date ( ... )

Returns a string containing a RFC 2822 formatted date.

Takes a hash reference containing values to use in generating this header. Valid keys are:

header_name

No default if not provided.

timestamp

UNIX timestamp. Defaults to current value of time() if not provided.

date ( ... )

Returns a date header containing a RFC 2822 formatted date. This is a convenience wrapper around rfc2822_date().

Takes a hash reference containing values to use in generating this header. Valid keys are:

header_name

Defaults to 'Date' if not provided.

timestamp

UNIX timestamp. Defaults to current value of time() if not provided.
