I changed the script a little:

if ($what=="download") {
   if (is_array($privatemessage)) {
//	        header("Content-disposition: filename=messages.txt");
//	        header("Content-type: application/octet-stream");
//	        header("Pragma: no-cache");
//	        header("Expires: 0");
	
     while(list($key,$val)=each($privatemessage)) {
            $downloads=$DB_site->query_first("SELECT touserid,fromuserid,dateline,title,message FROM privatemessage WHERE privatemessageid='$key' AND userid=$bbuserinfo[userid]");
            $tousername=$DB_site->query_first("SELECT username FROM user WHERE userid='$downloads[touserid]'");
            $fromusername=$DB_site->query_first("SELECT username FROM user WHERE userid='$downloads[fromuserid]'");
            $msgdt = vbdate($dateformat,$downloads[dateline]);
            $msgtm = vbdate($timeformat,$downloads[dateline]);
            $wordwrap = wordwrap($downloads[message],75,"\r\n");
	            
   $dump .= "\r\nDate/Time Sent: $msgdt, $msgtm\r\n";
   $dump .= "from: $fromusername[username]\r\n"; 
   $dump .= "To: $tousername[username]\r\n";
   $dump .= "Subject: $downloads[title]\r\n\r\n";
   $dump .= "$wordwrap\r\n";
   $dump .= "\r\n==========================================================================\r\n";

} //end while

  mail("$bbuserinfo[email]","Download Private Messages","$dump","From: Title of your board <no_reply_emailaddress>");

  eval("standarderror(\"".gettemplate("pm_download_complete")."\");");
 exit;
	    
} else {
  eval("standarderror(\"".gettemplate("error_pmnoselected")."\");");
  exit;
  }
}

Now the messages are send to the users emailaddress. In the template "pm_download_complete" you can warn them to check the email before deleting the messages.
