Answer 1

This site provides a script that they say works.

Here's my code sending vcard as attachement with no message:

    //create a boundary string. It must be unique
    $random_hash = md5(date('r', time())); $alt_random_hash = md5(date('r', time()+1)); 

    //read the atachment file contents into a string, 
    //encode it with MIME base64, 
    //and split it into smaller chunks 
    $attachment = (chunk_split(base64_encode(file_get_contents($url))); 
    $filename = "Alain_Leblanc.vcf";    

    // Write the email message (which will become an attachement)
    $headers .= "
    MIME-Version: 1.0 
    From: [e-mail] 
    Reply-To: [e-mail] 
    Content-Type: text/x-vcard; charset=utf-8; name=$filename; boundary=$random_hash  
    Content-Disposition: attachment; filename=$filename 
    Content-Transfer-Encoding: base64

    --$random_hash 

    $attachment

    --$random_hash-- 
    ";

    //send the email  
    $mail_sent = @mail($_POST['userEmail'], "Fiche contacts d'Alain Leblanc", "", $headers); 
    // display email result in browser
    echo $mail_sent ? "rand: ".$random_hash ."<br/>Alt: ".$alt_random_hash."<br/>".$headers : "Mail failed";
