Measuring the world's biggest email domains (fwd)

Subject: Measuring the world's biggest email domains

Hi Jason,

I am the chairman of a German eco working group about 
Sender-Authentication (http://www.eco.de/arbeitskreise/sauth.htm), in 
this context I started http://www.agitos.de/dkim-reputation-project.html 
which reveals interesting results: especially the blocking of single 
spammer accounts coming from ISP mail domains is an interesting +.

Now I want to measure the world's biggest email domains to forgive more 
spammers to "big" ISP domains than I would do for domains of a smaller 
size.
For this measurement I scripted a small Spamassassin-Plugin: 
http://www.agitos.de/pub/ReportDomainHit.pm with which a participant 
reports alleged sender domains to our UDP logging server.

Some people of the eco working group already installed this plugin and I 
get some interesting results, but - no doubt - the picture of global 
domain mail rates is very "German" at time.
Therefore I am looking for people from all around the world who might 
like to participate in this measurement (not too many to keep things 
working). Every participant will get the aggregated, static information 
after the measurement if liked.

It would be great if you could forward this message to admins who might 
like to support this anti-spam project (it is totally uncommercial, I'm 
doing all the DKIM stuff in my leisure time).

Best regards,
Florian

I'm very surprised to see this.  I've been working on a similar
project at UNC-Charlotte since August of 2007, and I had not
heard of its existence.  Our project is called RepuScore.

http://isr.uncc.edu/RepuScore/

I'm an undergraduate computer science student attached to RepuScore
as my required senior project.  I work as a coder and data collector
for PhD Candidate Gautam Singaraju, and Dr. Brent Kang, who are the 
main researchers.  We have published several well received papers at
conferences in the US.

It has become clear to me that reputation for authenticated
domains is the next big weapon in the fight against spam.  The only
remaining uncertainty is who will have the first and/or best deployment.
