I know I have brought up this issue on this list before, and sorry for the
persistence, but having 7 different rules adding scores for the IADB
whitelist still seems either ridiculous, or outright suspect:
-0.2 RCVD_IN_IADB_RDNS RBL: IADB: Sender has reverse DNS record
[199.127.240.84 listed in iadb.isipp.com]
-0.1 RCVD_IN_IADB_SPF RBL: IADB: Sender publishes SPF record
-0.1 RCVD_IN_IADB_OPTIN RBL: IADB: All mailing list mail is opt-in
-0.0 RCVD_IN_IADB_SENDERID RBL: IADB: Sender publishes Sender ID record
-0.0 RCVD_IN_IADB_LISTED RBL: Participates in the IADB system
-0.1 RCVD_IN_IADB_DK RBL: IADB: Sender publishes Domain Keys record
-0.1 RCVD_IN_IADB_VOUCHED RBL: ISIPP IADB lists as vouched-for sender
It really raises some very uncomfortable questions regarding the impartiality
of SA and/or its anti-spam capabilities. And by the way, this message is
definitely unsolicited, and in now way we gave any sort of permission or
consent to this company or its "affiliates" to email us - so the whole "All
mailing list mail is opt-in" is nonsense.
And why have "Sender has reverse DNS record" and "Sender publishes SPF
record" as separate IADB rules - when SA itself already checks for these?
Isn't this just a glaring way of pumping up SA scores for the IADB
subscribers?
Don't assume malice right off the bat. More likely it is that IADB
provides all those status codes and SA exposes a rule for each, with
minimal scores, to allow local tuning if desired.
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" ("double opt-in").
The scores appear hardcoded (50_scores.cf) vs. from masscheck
(72_scores.cf) so they may be *very* stale.
