I know I have brought up this issue on this list before, and sorry for

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?
Once in a while, even the best senders can get a bad customer of theirs
that obtained email addresses by a violation of their terms and conditions.
Just block that sender with a local "blacklist_from *@example.com" entry
and report it to SpamCop. If the message headers have any abuse
reporting information then send the headers there too. They should do
their own internal investigation and shutdown that bad customer of theirs.
That is still beside the point. There is simply no reason in the
interest of SA as an antispam solution to publish all those rules. One
or two rules would be more than enough. I know I can block this and that
in SA, and tweak rules all the time - but I am concerned when the
default settings in SA effectively facilitate marketing companies to
stuff my Inbox full of junk. In that case you would achieve better
results not using SA at all. As to reporting bad senders and "internal
investigation" - my experience shows that doesn't get very far with any
providers.
