Hello All,
I am a graduate student working on email reputation protocols. We have
been developing open-source reputation algorithm to compute sender's
reputation based on inputs at any deployed location.
http://isr.uncc.edu/repuscoreThe idea is that at multiple receivers, administrators can collect
spam, ham numbers etc. for different senders based on their emails.
Using this, we compute sender reputation. We have developed a
SpamAssassin plugin that collects such information and dumps it to a
local MySQL servers. Our scripts compute reputation that can be
deployed at your domain. If you are willing to share information, you
could do so to get a global view of senders.
