请给个实例吧，谢谢

sendmail + Mimedefang 什麼都能做!

/etc/mail/mimedefang-filter:

1. 
   
2. sub filter {
   
3. my($entity, $fname, $ext, $type) = @_;
   
4. if (filter_bad_filename($entity)) {
   
5.         md_syslog('info',"BAD FILE EXT: filename=$fname, type=$type");
   
6.         return action_bounce("An attachment of type $type, named $fname was not transmitted","554","5.7.1");
   
7. }
   
8. }
   
9. 
   
10. sub filter_bad_filename  {
    
11. my($entity) = @_;
    
12. my($bad_exts, $re);
    
13. $bad_exts = '.*';
    
14. $re = '\.' . $bad_exts . '\.*$';
    
15. return 1 if (re_match($entity, $re));
    
16. return 0;
    
17. }
