If it is truly static, as in, you will always get that IP, that is used just for you, no matter if you switch off your DSL for a week then back on again, and your ISP complies with all the other rules that SORBS likes to enforce then you could possibly get this decision reversed. On the other hand you may find it easier to get the people you mail to whitelist you or stop using this DNSBL. Or even easier, you could smarthost through a machine which does not a have a reverse DNS that looks like any old domestic DSL. (Not saying you are wrong to do what you do, just that you are overley optimistic to expect it to work that well in today's Internet) > Is this a new sorbs idea? No. Let's not have the SORBS thread again, hey?
