A LOT of Irish and UK ISP ranges get in there on a regular basis, so we
had to stop blocking on it a few months ago - digging emails out of
quarantines can get to be tedious - and now score based on it, which
gives much more accurate results.

We are primarily a hosting company, but also offer email filtering
services to 3rd parties. It is unlikely that a corporate IP range will
be listed, but as a large proportion of both our clients and our
clients' clients are not using fixed IPs we see a lot of issues with
Esat, Eircom and other ISPs.

The Spamhaus listing criteria is not at fault, blocking based on it is
unfortunately.
If you score based on XBL/SBL you will not see a drop in your success
rate, as no one rule is going to push an email over the limit (or keep
it under it)
