Have you tried all 3 of the routes listed at 
http://www.au.sorbs.net/faq/dul.shtml ?

Something they don't tell you on the web page is that they ignore TTL and 
cache your DNS for a relatively long time.  If you tried for automated 
removal and your rDNS wasn't SORBS-compliant, automated removal isn't 
going to work for some number of days (I forget how many) even after you 
have made your rDNS SORBS-compliant.

With rDNS like that...good luck.  Go read

change your rDNS, wait a few days, and maybe you'll have a chance.
