My mail function is as follows

add_action('wp_ajax_order_processing', 'order_processing');
function order_processing(){
include 'mail-translations.php';

require_once( ABSPATH . 'wp-admin/includes/file.php' );
global $wp_filesystem;
$upload_dir = wp_upload_dir();   
$dir = trailingslashit( $upload_dir['basedir'] )  . 'order-confirm/';

WP_Filesystem();
$wp_filesystem->mkdir( $dir );

$build_id=md5(uniqid(cvf_td_generate_random_code(), true));

$message = "<p>Hello</p>";    

$mpdf = new mPDF('utf-8', 'A4-P'); 
$mpdf->debug = true;
$mpdf->dpi = 150;
$mpdf->img_dpi = 150;
$mpdf->setAutoTopMargin = 'stretch'; 
$mpdf->setAutoBottomMargin = 'stretch';

$src = get_template_directory_uri() . '/images/rsz_bomann-logo-black.png';
$mpdf->SetWatermarkImage($src);
$mpdf->showWatermarkImage=true;
$mpdf->SetHTMLHeader('');
// PDF footer content                      
$mpdf->SetHTMLFooter('');
$mpdf->SetFont('helvetica');


$mpdf->WriteHTML($message); // Writing html to pdf
// FOR EMAIL

$content = $mpdf->Output( $dir . "wardrobe-".$build_id.".pdf", 'F'); 
$content = chunk_split(base64_encode($content));

$attachment = $upload_dir['baseurl'] . "/order-confirm/wardrobe- 
".$build_id.".pdf";


// Set Mail Headers
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type: text/html; charset=" . get_bloginfo('charset') . 
"" . "\r\n";

$subject = __('Order Confirmation for Order No. ', 'skapnet');

$order_mail = wp_mail("[email protected]", $subject, 'message' , 
$headers, array($attachment));

echo $order_mail;

}

Attachment returns an absolute path from the server. Because when i pasted it in the url, I got the pdf file. The mail also gets sent, but without the attachment. Please help.

You said in your OP that the absolute path was returned, but you are using the 'baseurl' value which gives you a URL to the file that you can browse to. That's a URL, which is not the same as the path to the file in the file system.

This line is your issue:

$attachment = $upload_dir['baseurl'] . "/order-confirm/wardrobe- 
".$build_id.".pdf";

This gives you a URL like this:

http://yoursite/directory/order-confirm/wardrobe-something.pdf

You can't attach a file to an email from a URL. You need the file path to the file on the server so you can attach it. Use the basedir value to build the file path instead.

$attachment = $upload_dir['basedir'] . "/order-confirm/wardrobe- 
".$build_id.".pdf";

The basedir result will give you something like the following:

/yourserver/somepath/directory/order-confirm/wardrobe-something.pdf

With the path to the file, you can attach it to your email.

Here's your function revised to use basedir instead of baseurl (noted with a comment where I changed it):

add_action('wp_ajax_order_processing', 'order_processing');
function order_processing(){
    include 'mail-translations.php';

    require_once( ABSPATH . 'wp-admin/includes/file.php' );
    global $wp_filesystem;
    $upload_dir = wp_upload_dir();   
    $dir = trailingslashit( $upload_dir['basedir'] )  . 'order-confirm/';

    WP_Filesystem();
    $wp_filesystem->mkdir( $dir );

    $build_id=md5(uniqid(cvf_td_generate_random_code(), true));

    $message = "<p>Hello</p>";    

    $mpdf = new mPDF('utf-8', 'A4-P'); 
    $mpdf->debug = true;
    $mpdf->dpi = 150;
    $mpdf->img_dpi = 150;
    $mpdf->setAutoTopMargin = 'stretch'; 
    $mpdf->setAutoBottomMargin = 'stretch';

    $src = get_template_directory_uri() . '/images/rsz_bomann-logo-black.png';
    $mpdf->SetWatermarkImage($src);
    $mpdf->showWatermarkImage=true;
    $mpdf->SetHTMLHeader('');
    // PDF footer content                      
    $mpdf->SetHTMLFooter('');
    $mpdf->SetFont('helvetica');


    $mpdf->WriteHTML($message); // Writing html to pdf
    // FOR EMAIL

    $content = $mpdf->Output( $dir . "wardrobe-".$build_id.".pdf", 'F'); 
    $content = chunk_split(base64_encode($content));

    // Use 'basedir' instead of 'baseurl':
    $attachment = $upload_dir['basedir'] . "/order-confirm/wardrobe- 
    ".$build_id.".pdf";


    // Set Mail Headers
    $headers = "MIME-Version: 1.0" . "\r\n";
    $headers .= "Content-type: text/html; charset=" . get_bloginfo('charset') . 
    "" . "\r\n";

    $subject = __('Order Confirmation for Order No. ', 'skapnet');

    $order_mail = wp_mail("[email protected]", $subject, 'message' , 
    $headers, array($attachment));

    echo $order_mail;

}
