Re: [Asrg] Please critique my anti-spam system

2005-01-06 02:32:30

I suspect that many of the participants of this list use and manage email
in a way that
is very different than the way that the average Joe does.

Professionally and with expertise you mean?

Ergo the flaws in my system (such as graphical support) may be
absolutely intolerable to the people involved with the
ASRG but these same flaws may be trivial to the average Joe.

But surely it is the professionals and the experts whom you wish to
convince of your proposal's
efficacy and desirability? Why else have you asked them to criticise your
proposal?

It seems to me that you hope to achieve the approval of this group but are
not prepared to
compromise your pet project in response to well informed, well intentioned
and cogent points
raised against it.
If you are only interested in appealing to the average Joe I suggest you
seek your approval
elsewhere, where you may receive a less honest and more acceptable
palliative review.

Eliminating spam for most, if not all people, would be an accomplishment.

No doubt. However I'm quite sure that mail administrators in ISP's and
corporations the world over
would look in dismay at cost of accomodating the use of a system which
requires that an outgoing
message be sent for every unwanted incoming message.

There is still some concern that the bounces will "spam" innocent people.

If we arbitrarily guess

Ah yes, a good solid "arbitrary guess"

that 1 out of 50 forged spam return addresses represents a real active
account,
and if we assume that bounces will only be sent back to 5% of spams after
filtering,
then we would have a 'bounce spam' problem that is only 1/1000th the size
of the spam
that is being sent out.

Of course this is an "arbitrary guess" and does not represent anything like
the real world.
What about those virii which send mail floods with real addresses? I seem
to recall several occasions when
these floods resulted in real headaches for sysadmins trying to cope with
the bounces.

 This is not even taking into account the ease with which a bounce can be
prevented from reaching a user if that user had not sent out the
corresponding email.

Preventing its receipt is one thing, preventing its transport is quite
another.

I do not believe that this will be the flaw that sinks this system.

Perhaps not, but don't underestimate the intelligence of the people who
will be required to make the
commercial decision to adopt your proposal.
