Hi all,
Has anyone given any thought to special rules or methods designed to
catch greymail? That is, mail that perhaps may be opt-in, but abusive,
like marketing mailing lists or newsletters?
This might include mail with List-Unsubscribe headers, but that's not
necessarily enough to use to block an email.
I've written a handful of rules based on Received headers for mail
servers like 'businesswatchnetwork.com' or 'list-manage.net' etc, but
there's obviously just too many of them and it's time-consuming.
Any ideas for improving this process?
Any thoughts on how the typical marketing email should be scored with bayes?
Perhaps there's a DNSBL or other RBL out there whose purpose is to
identify marketing domains?
Is anyone interested in sharing resources to start such a thing?
from tec side there is not really a difference
between marketing and other mails, dealing with their domains
might never end , but you can always use your own a reject list on smtp
level cause why should you do expensive content filter to known not
wanted domains.
At the end ,at a server with many different users you will see that some
marketing is really wanted by some users, but others like to see it
so best way for this are users own white/blacklists after you filtered
the most bad things global.

I think Alex is envisioning something more like DCC in severity, where
it's not actually a blacklist but uses the RBL functionality to apply a
light score penalty.
