$mail->Host = "email-smtp.us-east-1.amazonaws.com";
$mail->Port = 25;
$mail->Username = "support#example.com";
$mail->Password = "*******";
//
$mail->SetFrom('support#example.com', 'Example'); //from (verified email address)
$mail->Subject = "Email Subject"; //subject
//message
$body = "This is a test message.";
$body = eregi_replace("[\]",'',$body);
