[LINK] Message for Craig Sanders

(Sorry to do this to evereyone else, but I can't email Craig direct - 
and this is a topic that's been discussed here before ;)

Craig, I tried to send you an email, and got bounced because:

<cas at taz.net.au>: host taz.net.au[203.16.167.1] said: 550 Service 
unavailable;
     Client host [203.113.200.177] blocked using dul.dnsbl.sorbs.net; 
Dynamic IP
     Address See: 
http://www.dnsbl.sorbs.net/cgi-bin/lookup?IP=203.113.200.177

Interestingly, as per the headers:

My mail goes from me, through a static host, to you.  It appears that 
you're blocking based on the client address, not on the mail server 
address.  That means that I can't send you email, even though I'm 
sending through a legitimate server (and am, in fact, a legitimate 
sender of email, not a spammer ;)

The IP I'm on is listed in SORBS as being dynamic - which it is, and 
which is why I send through mx3.paradigm4.com.au, which is a static box.

Can you re-tune your filtering, or is there a legit reason for 
disallowing mail through static boxes from dynamic addresses?
