Are these IP addresses on CBL?
I did a spot check of a recent attack. The email address was
jabradb...@kanawhascales.com <mailto:jabradb...@kanawhascales.com> and
it got signed up to 12 lists during May 17 and 18. Amazingly, whoever
is on the other end of that address clicked to confirm every one of
those confirmation messages. All confirmation clicks appear to come
from a netblock owned by Barracuda Networks... Hmm...
Which netblock was that?
