Intruder alert!

Could someone forge an error reply to that message, so that our list
doesn't get put on their spam list?  (And, of course, if someone could
track them down physically and break their legs, so much the better!)

Actually, now that this has started, the proper way to go may be to
start blocking postings to the lists from anyone not on them.  On the
down side, this means that people must send their postings from the
address they're subscribed as.

The other downside is that anyone in need of help has to subscribe before
they can ask their question.

Why don't we make it known (In the periodic developers FAQ posting?)
that we do not accept unsolicited email and that we will charge a fee
($50 per line per subscriber :).  I for one would be more than happy
to do the detective work to track these down.  As for what to do with
the money -- perhaps we should see how much we get first.

If we want to do this, we should pick some price and mention it in our
FAQ.

	Even better, I have to get my next set of filters in place...that
doesn't allow connects from SPAM sites :)

> -tih (who hopes all UCE senders die slow and painful deaths)

	Makes two of us, but closing the lists isn't the way to go...

This won't work. We have a similar policy with the Debian project. But we
have yet to see money. No lawyer will help you there. And the spammers won't
send money because they like the policy. :-(

I think the best way is to install anti-spamming software.

No, but if we can figure out who did it and send them a bill for our
services rendered (reading their spam), which they solicited by
posting it (as per the conditions in our FAQ, then we can turn them
over to a collection agency if they don't come through.

Of course tracking down the poster is a trick in the first place.

I think any such method can be circumvented.  The only long-term
solution is to make spamming unprofitable.  One thing that would go a
long way is to reverse-verify the sender's address.  If the sender has
forged this, the mail is dropped and we get the sound of one spam
clapping :) The problem is that most sites nowadays won't verify email
addresses.  This sounds like a good project for a free relational
database. Anybody know of any good ones out there? :)

	Actually, I currently have two anti-spam filters in place...one of
which verifies the domain of the poster...its not 100% perfect, but it
does a pretty good job of it...

I am running software that allows me to check for reverse DNS on a
connection and refuse SMTP connections if they don't have any.  In
addition I can refuse email from known spam sites and even from sites
that use known spammers for their DNS so they can't get throwaway
domains and drop them before the Internic kills them for non-payment.

At home I implement this fully and find it very satisfying.  A lot of
spam gets dropped.  I tried to do something similar at vex.net, my
ISP, but the testing I did suggested that customers just wouldn't
stand for it.  There are a lot of broken sites without proper reverse
DNS and they just refuse to fix themselves.  I suspect if we had to
verify addresses we would be hearing echoes up and down our password
file.

Somebody out there wrote a program that puts new emailers mail into purgatory
until they respond to an automated request to verify.  After a while, purgatory
gets purged.  If they reply, tho, then the message is released.

This sounds interesting.

That doesn't sound too bad, especially for a mailing list like this.
We could even "prime" it by adding the current subscribers to the
list.

	I have the anti-relay spam filter and the reverse DNS ones
installed on Hub.Org and at work (work has ~5000 mail users, no complaints
after a year being in place)...the only one I haven't added to Hub.Org yet
is the 'spam list', which I do have at work.  Next one to move over, I
guess...

	I don't find it too bad...complaints from our users are pretty
much zero (even from the professors) as far as email and filtering is
concerned...most ppl are happy because spamming is reduced...
