I don't know how this will work but I'm building the data now. For
those of you who are familiar with Day old bread lists to detect new
domains, as you know there's a lag time in the data and they often
don't have data from all the registries. So - here's a different
solution.
What I'm thinking is to accumulate every domain name that interacts
with my system and storing it in a list. Eventually after a week or
so I should have a good list. Then the idea is to do a lookup to see
if a new domain is NOT on the list. This will catch all really new
domains, but will have some false positives. But - if it is mixed
with other conditionals it might be a good way to detect and block
spam from or linking to tasting domains.
So, If for years I send mail to hundreds of people in my county, but
never anything to your spamtraps or your legitimate mail, and then one
day I decide to send you a single piece of mail, you will blacklist me
as DOB?
No - that's not how it works. Being a stranger to the list doesn't get
you blacklisted. It's just a factor that when combined with other
factors indicates it's spam. And generally URI spam. I'm just using this
as a way to discover new domains by what's not on a list as opposed to
what is on a list.
And I don't yet know if it will work. I'm still building the list. I
just wanted to throw the concept out there and see if it sparks
innovation. It might turn out to be a dead end.
