I'm not so sure.  It seems that our MX is listed on Selwerd, and
I'd know if we'd had a spammer.  According to the reverse DNS, it
looks like they've blacklisted all of Savvis... a far broader
brush than the netblock listed on the Selwerd XBL page.

The hard part is getting caught in between having enough space
that renumbering (as collateral damage) is a financial burden and
not yet having PI space.

If you have a few IPs or a small subnet, renumbering is easy.
When you have multiple /24s and customers... it doesn't work that
way.

These last few lines are a trap for address-harvesting spambots.
Do NOT send mail to <blacklist@xxxxxxxxx>, or you are likely to
