for what reason no use phpmailer? example for an attachment:

function mandaMail ($nombredest, $maildest, $asunto, $cuerpo) {
require_once("mailer/class.phpmailer.php");
$mail = new PHPMailer(true);
$mail->IsSMTP();

try {
    $mail->Host = "xxxx"; $mail->Port = 25; // smtp server
    $mail->SMTPAuth = true;
    $mail->Username = "xxxx"; // smtp username
    $mail->Password = "xxxx"; // smtp pass
    $mail->AddReplyTo("xxxx", "xxxx"); // email & name
    $mail->SetFrom("xxxx", "xxxx"); // similar to up value

    $mail->AddAddress($maildest, $nombredest);
    $mail->Subject = $asunto;
    $mail->MsgHTML(file_get_contents($cuerpo));

    $mail->AddAttachment("xxxx", "xxxx"); // attachments directory, attachment name (ie: dir/blah.jpg, blah.jpg)
    $mail->Send();

} catch (phpmailerException $e) { echo $e->errorMessage();
} catch (Exception $e) { echo $e->getMessage(); }
