The problem with that is it assumes that, for spam, either: 1) the return address is the spammer's address, or 2) the return address is the owner of the (probably infected) system that sent the spam.


Neither of those is likely to be true. Most spam will NOT have a correct return address, just to avoid getting deluged with bounce messages from places that decide the recipient doesn't exist halfway through the local delivery process. And they're NEVER the email address of the owner of the sending machine. All current trojan/virus spam engines forge From: headers using addresses harvested from various places on the infected machine or even other addresses from the list it's trying to deliver to.


So in the case of spam all you're doing is taking the unsolicited email that you got and using it to generate unsolicited email for someone else.


The only accurate way to identify the source of spam is from the Received: header generated by your mail server when it accepts the email. And all that gives you is the IP address of the sending system. There's no way for anyone other than the infected user's ISP to associate that information with a username/email address.


While generating an auto-ack for submissions seems like a nice gesture, in the case of spam all it does is aggravate the situation. It might be more effective to do something like comp.risks does now -- ask submitters to tag submissions with a unique identifier in the subject line. Or create a unique email address that's recognizable but not harvestable (maybe by adding a tag line to postings with instructions on how to construct the submission address).

[TELECOM Digest Editor's Note: First of all, if I were interested in 'doing like comp.risks does' that's one thing, however although I do have many regular correspondents here, there are also many newer and inexperienced netizens who write me to _ask questions_ about how _telephones work_, etc. I cannot have a system where if someone wishes to write me, he has to include 'keyword' in the subject line. I do not have a closed-loop of my friends or enemies as my only writers. Far too much good letters would get trashed that way. And with twenty some years of postings in our own archives here and many other places, it would take a long time to teach people how to construct the submission address.

Let's just face it: passive filtering of email has been from the beginning been a dismal failure. All it has gotten us is an ever increasing ratio of spam/scam to legitimacy; a ratio that now is in excess of 80-85 percent and will eventually (as close as is mathemat- ically possible) reach 100 percent; I suppose it could get to 99.99998 percent spam/scam, there will always be a few fools trying to send out legitimate email. _Filtering does not work_. Filtering is the notion that 'if we ignore them, they will go away' and I can tell you that they will not. Filtering is just a deluded act of self-denial which refuses to admit how bad things have gotten. We continue to keep our filters running overtime; and a whole branch of software writing, a whole new industry -- anti-virus, anti-spam software protection -- has developed to appease those folks who want to use it.


You may recall my concept several years ago of a 'Business Directory' which listed the 800 numbers of spammers; the idea was to do as they asked, and call them _on their 800 number_ to inquire about their 'product' or 'service'. Even though Jeff Slaton wound up having to damn near mortgage his home to pay his bill to Southwestern Bell after his 800 number was published here, I did not hear any of the now, all too common excuses and wimpering about doing the essence of DDOS on his phone lines. I did not hear anyone wondering 'oh what if he decides to sue me for this _illegal_ act I am doing'; i.e. calling him as requested to complain about the spam.


But now, ICANN is in the picture, and we suddenly hear how _anything_ at all we do to agressively fight spam/scam (instead of just passively rolling over and accepting it, using filters like the defective and faulty condoms they are) is illegal, immoral, etc.


That's the genius of the Blue Security approach. It works essentially like my Business Directory concept. Telephone the _actual offender_ (not just some sap whose computer got compromised or some sysadmin who can't get his act together) and inform _the actual offender_ what you want. And its automated, and it does not involve email at all. The netizen goes to the website of _the actual offender_ and fills in the blanks on his page explaining what is wanted, which is what he asked us to do, is it not? Admittedly, the answers I would give are not the answers he wanted, but neither were the answers most of you gave when you telephoned the 800 number of the _actual offender_. And in that instance, telephone numbers are a lot like IP addresses. Yes, people in the middle can make changes in how you get from here to there, and yes, a sufficient number of connections all at one time will cause some hassles. But that is neither here nor there.
