NAME¶
Email::Send - Simply Sending Email
WAIT! ACHTUNG!¶
Email::Send is going away... well, not really going away, but it's being
officially marked "out of favor." It has API design problems that
make it hard to usefully extend and rather than try to deprecate features and
slowly ease in a new interface, we've released Email::Send
er which
fixes these problems and others. As of today, 2008-12-19, Email::Sender is
young, but it's fairly well-tested. Please consider using it instead for any
new work.
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 of this software is to be small and simple,
easy to use, and easy to extend.
Constructors¶
- new
-
my $sender = 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 received.
This is useful if you are sending in bulk.
METHODS¶
- send
-
my $result = $sender->send($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 = $sender->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?
$sender->mailer('SMTP')
if $sender->mailer_available('SMTP', ssl => 1);
Given the name of a mailer, such as "SMTP", determine if it is
available. Any additional arguments passed to this method are passed
directly to the "is_available" method of the mailer being
queried.
Writing Mailers¶
package Email::Send::Example;
sub is_available {
eval { use Net::Example }
}
sub send {
my ($class, $message, @args) = @_;
use Net::Example;
Net::Example->do_it($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 $FIELD];
use Return::Value;
sub is_available {
eval { use LWP::UserAgent }
}
sub send {
my ($class, $message, @args);
require LWP::UserAgent;
if ( @args ) {
my ($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 $sender = Email::Send->new({ mailer => 'HTTP::Post' });
$sender->mailer_args([ 'http://example.com/incoming', 'message' ]);
$sender->send($message);
$sender->send($message2); # uses saved $URL and $FIELD
