NAME

Email::Send - Simply Sending Email

SYNOPSIS

use Email::Send;

my $message = <<'__MESSAGE__';
To: recipient@example.com
From: sender@example.com
Subject: Hello there folks

How are you? Enjoy!
__MESSAGE__

my $sender = Email::Send->new({mailer => 'SMTP'});
$sender->mailer_args([Host => 'smtp.example.com']);
$sender->send($message);

# more complex
my $bulk = Email::Send->new;
for ( qw[SMTP Sendmail Qmail] ) {
    $bulk->mailer($_) and last if $bulk->mailer_available($_);
}

$bulk->message_modifier(sub {
    my ($sender, $message, $to) = @_;
    $message->header_set(To => qq[$to\@geeknest.com])
});

my @to = qw[casey chastity evelina casey_jr marshall];
my $rv = $bulk->send($message, $_) for @to;

DESCRIPTION

This module provides a very simple, very clean, very specific interface to multiple Email mailers. The goal if this software is to be small and simple, easy to use, and easy to extend.

Constructors

new()

my $mailer = Email::Send->new({
    mailer      => 'NNTP',
    mailer_args => [ Host => 'nntp.example.com' ],
});

Create a new mailer object. This method can take parameters for any of the data properties of this module. Those data properties, which have their own accessors, are listed under "Properties".

Properties

mailer

The mailing system you'd like to use for sending messages with this object. This is not defined by default. If you don't specify a mailer, all available plugins will be tried when the send() method is called until one succeeds.

mailer_args

Arguments passed into the mailing system you're using.

message_modifier

If defined, this callback is invoked every time the send() method is called on an object. The mailer object will be passed as the first argument. Second, the actual Email::Simple object for a message will be passed. Finally, any additional arguments passed to send() will be passed to this method in the order they were recieved.

This is useful if you are sending in bulk.

Methods

send()

my $result = $mailer->send($message, @modifier_args);

Send a message using the predetermined mailer and mailer arguments. If you have defined a message_modifier it will be called prior to sending.

The first argument you pass to send is an email message. It must be in some format that Email::Abstract can understand. If you don't have Email::Abstract installed then sending as plain text or an Email::Simple object will do.

Any remaining arguments will be passed directly into your defined message_modifier.

all_mailers()

my @available = $mailer->all_mailers;

Returns a list of availabe mailers. These are mailers that are installed on your computer and register themselves as available.

mailer_available()

# is SMTP over SSL avaialble?
$mailer->mailer('SMTP')
  if $mailer->mailer_available('SMTP', ssl => 1);

Given the name of a mailer, such as SMTP, determine if it is available. Any additional arguments passed to this method are passed directly to the is_available() method of the mailer being queried.

Writing Mailers

package Email::Send::Example;

use UNIVERSAL::require;

sub is_available {
    Net::Example->require;
}

sub send {
    my ($class, $message, @args) = @_;
    Net::Example->require;
    Net::Example->do_it($message) or return;
}

1;

Writing new mailers is very simple. If you want to use a short name when calling send, name your mailer under the Email::Send namespace. If you don't, the full name will have to be used. A mailer only needs to implement a single function, send. It will be called from Email::Send exactly like this.

Your::Sending::Package::send($message, @args);

$message is an Email::Simple object, @args are the extra arguments passed into Email::Send::send.

Here's an example of a mailer that sends email to a URL.

  package Email::Send::HTTP::Post;
  use strict;

  use vars qw[$AGENT $URL $FIELD];
  use UNIVERSAL::require;
  use Return::Value;
  
  sub is_available {
	  LWP::UserAgent->require;
  }

  sub send {
      my ($message, @args);

	  LWP::UserAgent->require;

      if ( @args ) {
          my ($URL, $FIELD) = @args;
          $AGENT = LWP::UserAgent->new;
      }
      return failure "Can't send to URL if no URL and field are named"
        unless $URL && $FIELD;
      $AGENT->post($URL => { $FIELD => $message->as_string });
	  return success;
  }

  1;

This example will keep a UserAgent singleton unless new arguments are passed to send. It is used by calling Email::Send::send.

my $mailer = Email::Send->new({ mailer => 'HTTP::Post' });

$mailer->mailer_args([ 'http://example.com/incoming', 'message' ]);

$mailer->send($message);
$mailer->send($message2); # uses saved $URL and $FIELD
