Dear mailinglist-recipients,
I'm heading forward to an essay for IT class about actual spamblocking
mechanisms.
Doing some early research for my paper I found out that some
antispam-/mailsecurity-providers
like Barracuda Networks provide an live interconnection between their
appliances to have a nearly
live reaction on all their nodes to spam-sources.
Is there something similar for spamassassin?
As far as I found out spamassassin uses some real time blacklists to
check if a host (based on domain
name or ip) is a known source of spam.
But on which data are these RBLs based on?
Does every spamassassin-installation automatically provide data to RBLs
(or similar services)
and contributes this way to their services?
If that's the case, which information is shared by spamassasin?
Is there any other automatic contribution by a spamassassin-installation
to improve the further
development of spamassassin for example?
I would appreciate if you link any additional information sources you know.
Kind regards
Gregor
