[exim] bounces questions

Hello. Today i'm read some documents about BATV and VERP and now i'm
cunfused =)
Does this tehnologies need today (i'm use spf and dkim fjr all my
mails).

How can i block bounce messages that generate this php script:

<?php
$headers = "Return-path: <vase@???\r\n".
"Received: from 122.162.37.48 by ASPMX3.GOOGLEMAIL.com; Wed, 19 Aug 2009
15:50:35 +0530\r\n".
"Message-ID: <000d01ca20b6\$b0b689d0\$6400a8c0@medicinaln02>\r\n".
"From: medicinaln02@???\r\n".
"To: <fsdfsfsd43242fs@???>\r\n".
"Subject: =?koi8-r?B?68/MzMXLw8nRIPPUydfFzsEg88nHwczB?=\r\n".
"Date: Wed, 17 Sep 2009 15:50:35 +0530\r\n".
"MIME-Version: 1.0\r\n".
"Content-Type: text/plain; format=flowed; charset=\"koi8-r\";
reply-type=original\r\n".
"Content-Transfer-Encoding: 8bit\r\n".
"X-Priority: 3\r\n".
"X-MSMail-Priority: Normal\r\n".
"X-Mailer: Microsoft Outlook Express 6.00.2900.2180\r\n".
"X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2900.2180\r\n";

mail('fsdfsfsd43242fs@???','Header','Body',
$headers,'-fvase@??? -d -v ');
?>

(My address vase@???, i send to fake yandex.ru andress). Does BATV
do this for me? Is that possible to block such bounces withous BATV?

Can You give me some real life expamples of using VERP without mail
subscription service?

THanks!
