Anybody knows how they are these filtering measures in Finland?
Are they filtering technics or they're results of FICORA's regulation
in Finland abot "Information Security and Functionaly of email services"
There are few aspects of this "reduction". First the technical ones:
- mandatory limits on outbound and inbound port 25 usage for consumer
connections (most ISPs have interpreted this as "block" to anything else
than ISPs' MTAs).
- blocklist usage (generally ISPs won't tell which lists they use, so
you're out in the dark if something gets blocked)
- during virusbreaks, attachment filtering on the ISPs' MTA
- other limits on ISP's MTA usage (yet again, mostly cloack and dagger
stuff revolving around rate limiting)
Then others:
- misleading description on what was reported (report was "spam
reduction", when it should have been "reduction on spam reaching
end-user mailboxes for those users that use ISPs mailservers")
- misinterpreted statistics
- imaginary statistics
For most part the results are due to the non-technical actions. So, this
is actually a case of The Emperor's New Clothes.
There is a writeup on this report at
http://www.iki.fi/jhuhta/roskaposti_ei_vahentynyt.html . Unfortunately
it is in Finnish. I've asked the author for permission to translate it
in English.
