Correct me if I'm wrong, the principle disruption -- and I want to
emphasize disruption here -- I've seen is that a particular spam
indicator no longer works as expected. Is there more to this than that?
...
The list I've seen is:
- failing to reject spam based on NXDOMAIN for the envelope sender.
(What you term "the principle disruption")
- rejecting legitimate mail because some long dead DNS-based
blacklists are suddenly resolving
- HTTP spiders will fetch Verisign's robots.txt a lot as they
find bogus domains (e.g. typos in HREFs) resolving.
- HTTP users see a stalled screen instead of an error message as
their browsers wait for Verisign's overloaded HTTP server to
deliver its advertising.
