Justin Mason mentioned tms and TMDA
Can you provide any discussion of the success of these systems
in blocking spam? Are the users happy with these systems? If they are
successful, why haven't they been deployed more broadly? Are there any
IPR constraints that would prevent IETF working groups from discussing
similar approaches, etc...
Well, tms (apparently) became unmaintained, so TMDA was started. That's
got a lot of users out there.
The main issue it has (I hear), is that it requires configuration and
manual whitelisting of mailing lists, e-commerce sites, etc. Manual
intervention by the user is a big usability issue for spam filters,
since you start getting into a situation where they have to spend more
time configuring it than they would deleting the spam. ;)
