Well, it would be nice if your patch were listed on the qmail 
homepage.  Poor documentation as you say.

But your patch doesn't do what mine does - you use the INN wildmat pattern 
matching system, which is not very powerful.  I have embedded a Perl engine 
into qmail-smtpd which allows you to use Perl's excellent pattern matching 
system.  If you can show me how to block the range of IP addresses 
172.16.0.0 - 172.31.0.0 with one filter with your patch, I'll agree that I 
have rather foolishly reinvented the wheel.  Here's my regex to do the job:

/172.(?:1[6-9]|2[0-9]|31).[0-9]+.[0-9]+$/

One line, nice and simple.

regards,
Will
