But while the US-centric issues are not lost on me, it certainly seems that the majority of spammage originates from US ISPs. Perhaps this is based in some way on the free-wheeling entrepreneurial nature of US commerce or on the increasing tide of social indifference. But I digress... I am talking very specifically about US federal law, applicable to US citizens. The Internet is indeed a global phenomenon but when one leads, others may surely follow. I am not advocating laws which restrict uses of commercial networks. I am advocating restraint over those things that others can do to me which cost me money and thus, are theft. Federal law already (I believe) restricts what use others may enjoy of my resources without my permission. FAX and cellular phones cannot be used for purposes of advertising. Finally, what I am suggesting is perhaps a little more subtle than grotesque legal bludgeoning. Consider the potential impact that highly visible federal law would have on those who would consider this an effective means to market to others using resources for which they do not pay. One argument I have seen is that all we need do is get a single AUP to which all ISPs will adhere. When such a thing comes into existance, I believe it will be far too difficult to read the wonderful news, amid the 5000 spams waiting in my mail queue. I believe the chestnut about herding cats might have originated with the idea that we can get all ISPs to agree on any one thing. </rr> -- The Internet Company - info(a)internet.com We Bring Only Value to the Global Internet

How do you propose to deal with off-shore spammers? This isn't an issue for FAXing because an offshore FAX sender would have to pay international phone rates, which act as a natural deterent. However an e-mail message can be as quickly and easily sent from off-shore as it can be sent from within the U.S. Legislative solutions will also not address the ease of which someone can spam using someone else's name, not to mention the ease of routing the spam through other Internet hosts, including those which are offshore. It is bad enough today that when someone sends spam that appears to be from my institution (but is often only forged to appear that way), that I receive many complaints from people across the network. If such spam was against the law, I suspect that I would be visited by law enforcement agents, who will waste my time while I explain (or prove) that the spam did in fact not originate from my institution. Policies (and laws) which are not enforceable are often worse then no laws at all. -Jeff

Paul, none of the suggestions I have seen so far (in more than five years) offer something which 1. is an effective solution, 2. is technologically possible, and 3. places the burden of blame on the perpetrator. If you can propose a solution which does not imply: ...imaginary technology to intuit a commercial message from its content (can anyone say "content based routing"? ;) ...making the management of the affected resources more rigorous than current practice ...punishing the ISP for the actions of its customers ...complex or impossible deployment issues ...added administrative cost I and many others would LOVE to hear about it. I am the first to agree with Shakespere on the value of certain members of the legal profession. This time, however, I do not see any recourse. Do you? </rr> On 16 Oct 95 at 9:40, Paul Ferguson wrote: > Eek.

After contacting his ISP, I initially had problems with them because they flatly denied that the mail was originating from their host.

This provided the evidence that the mail was indeed originating from their host, and they took the appropriate action. -HWM

You should also investigate the MCI Routing Registery. The documentation can be found on http://infopage.mci.net.

This could be a Best Current Practice, quickly > published! Hm, this is already covered. RFC 1123 says: 5.2.8 DATA Command: RFC-821 Section 4.1.1 ... * The FROM field SHOULD contain both (1) the name of the source host as presented in the HELO command and (2) a domain literal containing the IP address of the source, determined from the TCP connection. ... DISCUSSION: Including both the source host and the IP source address in the Received: line may provide enough information for tracking illicit mail sources and eliminate a need to explicitly verify the HELO parameter. Thus, this is not a new suggestion (RFC 1123 is dated Oct 1989). Regards, - Håvard

-----BEGIN PGP SIGNED MESSAGE----- I would really like to see mailing lists starting to distribute *only* PGP-signed messages, with PGP key published in a keyserver with appropriate credentials. There already are mailers which call PGP automatically, so the user is not required to type something like ~| pgp -fsat every time. This is not a high magic. This is a matter of three lines of code, and some patience of the list maintainer. It is also good as it will proliferate good encryption software, and teach people how to protect themselves. - --vadim -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBMIIlOUDODjim2XUVAQFhPQP/dS+LMSX5eJ1x4v/nL3eHYlX1DmCAxt6M Uor3umYz7moHo8ztBe6NoMUj/ovncq4oQhqZEnXj6RtHXHX+zZbupVISnNw+GUUB E/TJTGRgTkyadqGINA5lHopZJp/tsQ9Rmn1PE6uQelLkkHJ9FS3J5gcpwewmRlQv oylV8EQ1P48= =oLiq -----END PGP SIGNATURE-----
