Anyone got some pointers on how to get off SORBS' Dynamic IP lists?

We've followed their RFC proposed static reverse DNS assignment naming and all elements of their FAQ.

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.
