Here you are evaluating SenderKeys in terms of the authority's algorithm
for when to auto-respond. What you assume is that for example, AccuSpam
is blacklisting individual addressses, which is not the case. AccuSpam
is counting the disapproval vs. approval ratio for a domain, then if it
is a spammer domain (one that sends > 99% spam from a probablistic
metric ... not pure ratio), then it blacklists the entire spammer domain
(e.g. gooddeals.com, a001.com, etc). The statistics theory prevents
blacklisting of domains that send some non-spam.
So here we are talking about a commercially available blacklist/whitelist.
And how many of these are available for senderkeys? And what are the costs
of using them? And is the MUA plug-in/patch free?
Given a message with a missing SenderKeys signature, SenderKeys will pass
the message to the "authority" (AccuSpam or spamassassin, perhaps) and the
authority will use whatever additional heuristics it chooses. If the
message has an invalid or incorrect signature, SenderKeys will presumably
block the message (bounce, drop, whatever the user wants at that point).
Hang on - I thought the "authority" only holds lists of those domains
without senderkeys, and challenges the mail address on that domain to get
their senderkey setup before the mail will get to the recipient. If the
"authority" actually does the spam filtering it might well be taking out
stuff I actually want, etc. Spam to you might be ham to me ;-)
You are getting me (and others) confused about the difference between
AccuSpam and SenderKeys.
Senderkeys is a mechanism - Accuspam is the paid for service you have to
subscribe to to use it ;-)
I am very happy to elaborate if you can please appeal to the list to
reinstate me. I have turned off my auto-respondeer.
I've noticed - but your brief and inglorious career on the mail-list was of
your own making. It's a pity you didn't introduce us to the mechanism and
leave the red-herring of accuspam out of it - even though that will be your
paycheck if the system ever gets going. Get youself a mail-list and we
might continue the discussion there.......
