I submitted a removal ticket a few weeks ago, an automated response was received saying "Sorry, your IP is considered a dynamically assigned IP and can't be removed."
We have a ticket in on the netblock, as well, if you're talking about the same netblock as I'm thinking of. It's been over a week and I haven't heard a thing; the only response I have received was an automatic response showing me lots of /29s and /30s from the block that aren't eligible for delisting.
The rub they have is that we use "li12-345.members.linode.com" as default reverse DNS. Based on their idea of an Internet Standard (and an
Internet Draft that has been expired for years; Trend Micro uses this too), they interpret this as a dynamic IP -- i.e., one given to dialup customers, or DSL customers -- which should not be sending mail. I have approached this issue with Trend Micro (who run DUL) and SORBS, and both want us to put "static" in the reverse DNS. While technically possible, it would be a drastic change and would break all of you for up to a few days. We're just not willing to do that to our customers.
While I cannot slight a provider on the Internet, I can say it has been extraordinarily difficult to get this netblock removed. Most of the blocklist entries were put into place before we even received the netblock in question -- I think it was with a home ISP before us. We will continue fighting this fight, but the complete yawn of silence from SORBS is not reassuring.
