*********************************************************************
Installation:

Copy class.phpmailer.php into your php.ini include_path. If you are
using the SMTP mailer then place class.smtp.php in your path as well.
In the language directory you will find several files like
phpmailer.lang-en.php. If you look right before the .php extension
that there are two letters. These represent the language type of the
translation file. For instance "en" is the English file and "br" is
the Portuguese file. Chose the file that best fits with your language
and place it in the PHP include path. If your language is English
then you have nothing more to do. If it is a different language then
you must point PHPMailer to the correct translation. To do this, call
the PHPMailer SetLanguage method like so:

// To load the Portuguese version
$mail->SetLanguage("br", "/optional/path/to/language/directory/");

That's it. You should now be ready to use PHPMailer!


A Simple Example:

<?php
require("class.phpmailer.php");

$mail = new PHPMailer();

$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "smtp1.example.com;smtp2.example.com"; // specify main and backup server
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = "jswan"; // SMTP username
$mail->Password = "secret"; // SMTP password

$mail->From = "[e-mail]";
$mail->FromName = "Mailer";
$mail->AddAddress("[e-mail]", "Josh Adams");
$mail->AddAddress("[e-mail]"); // name is optional
$mail->AddReplyTo("[e-mail]", "Information");

$mail->WordWrap = 50; // set word wrap to 50 characters
$mail->AddAttachment("/var/tmp/file.tar.gz"); // add attachments
$mail->AddAttachment("/tmp/image.jpg", "new.jpg"); // optional name
$mail->IsHTML(true); // set email format to HTML

$mail->Subject = "Here is the subject";
$mail->Body = "This is the HTML message body <b>in bold!</b>";
$mail->AltBody = "This is the body in plain text for non-HTML mail clients";

if(!$mail->Send())
{
echo "Message could not be sent. <p>";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}

echo "Message has been sent";
?>
