Hi Joe!
The proper procedure to request removal is to use the removal form:
http://www.surbl.org/surbl-analysis
If you are unable to use the removal form, then please use plain text email with all of the required removal information sent to whitelist@surbl.org (but the form is the preferred method)
I hope that helps.

Right...the problem is that the required removal information includes samples of email in which the listed URL (ibwmail.com) is part of the content, and there are no such emails; none sent by the entity in control of the domain, and none that we can find anywhere online.
That said, I note that the domain is now delisted - so, thank you, whomever facilitated that, although what I was actually looking for was information about why it was listed, so we could bash the senders over the head if need be. ;-)
