But why does SA have to expose a rule for each and every code IADB
So that users can implement their own policies if desired? So that
different rules can have a more granular effect on the inbound email
flow, without this being a simply binary affair (present, not present)?
More reasons come to mind, but it all boils down to exposing all the
available information to the users in order for them to make better
As I mentioned in one of my prior responses, I personally know of
operations that use that data granularity to their advantage.
SA is an antispam solution, IADB is a facilitator for the marketing
industry (in spite of their continuous protestations on this list).
The goals of the two are not the same. Surely SA can decide by itself
what is really useful from a spam filtering point of view - not churn
out whatever it gets passed by marketing whitelists? SA uses other
whitelists (some may I say a lot more useful than IADB), and it only
exposes one or two rules for each.
I doubt IADB is in a position to dictate to anyone how to use (or not)
the data it provides. Not SA, not anybody else. Participants in IADB
(listees and users) voluntarily act so. As someone else in this thread
pointed out, IADB provides a useful ham signal.
I think the goals of both are fairly aligned. An antispam solution is
not good if it blocks wanted email. IADB is conveying information about
the stated policies / practices of the sending organization. Assisted
with this information, SA can take better decisions about specific
pieces of email.
Also, there is RCVD_IN_IADB_DOPTIN, so RCVD_IN_IADB_OPTIN may be
"someone somehow gave us your name somewhere" (i.e. "single opt-in")
rather than "we confirmed you actually want to receive our garbage"
So effectively pretty useless, as if you ever made the mistake of
forgetting to untick the "receive email from our carefully selected
partners" in the past, you will never be able to take that consent
back as your email address gets passed from entity to entity. Consent
to be emailed marketing material is a joke - and SA shouldn't be a
facilitator - otherwise its value as a spam filter is gone.
I fail to see how SA is acting as a facilitator in this case. SA ships
with rules that look up all the available information about a piece of
email and then, hands this information to a set of rules that decide
what should happen to that email. You're objecting to the scores being
applied to those rules because you received one email that you believe
doesn't align with the results of one of those rules and want to drop
those rules from the distribution.
What would happen if the email you wanted came from a mail server listed
in Spamhaus? Would you then argue for removing rules using Spamhaus from
I would urge you to follow the advice of other list members and actually
report the misclassified spam so that involved parties can take action.
The scores appear hardcoded (50_scores.cf) vs. from masscheck
(72_scores.cf) so they may be *very* stale.
In that case maybe at least some of the rules should be removed then
In this case it seems to me that you already have a desired outcome and
will grasp at any shred of argument to justify it.
