Hello Sorry for my bad English, I'm German and soory therfore, that possibly I tell you "old stories". I've entried this list to translate an idea in the German news group de.admin.net-abuse.mail. This ist not my idea, but of Paul Lenz and I only want to report it.
The test contains the examination of all links in the body. You have to get the date of registration and to calculate the age of this urls. Of course for practal use you have to cache thoose whois-requests onto a central server and to provide a complete series of mta's. Mathias Leisi has written some small and draft scripts to run this cached whois-routines. http://matthias.leisi.net/archives/129-New-version-of-Domain-Age-DNS-Server.html http://matthias.leisi.net/archives/127-DNS-based-query-of-domain-age.html Mathias Leisi's opinion is that it is better to avoid a direct spam-ham-decision but to score the age of an url. < 5 days -> 5 Points < 10 days -> 3 Points < 15 Tage -> 1 Point >> 15 Tage -> 0 Points May be that this test is interesting for you.
