Forwarded mail almost always shows an 'envelope from' of the _forwarding_ party. Case in point: all email, sent to nanog is 'forwarded' to me, and the other readers of the list. It has an "inside address" (per the 'From:' header) of whomever authored the message. *BUT*, the 'envelope from', in the SMTP transaction is completely different: <owner-nanog(a)merit.edu> A _successful_ SPF check on 'merit.edu' would, hopefully include 198.108.1.26 (trapdoor.merit.edu) in the list of 'official outgoing mail sources. Ignoring for the moment the fact that Merit hasn't added SPF records to DNS yet. :) Same thing applies for 'simple' forwarding via sendmails '~/.forward' mechanism. the mail server 'accepts' the mail from the original source, and then 're-sends' to the new destination. That re-send originates as the _forwarding_party_, WITH an 'envelope from' of that forwarding party, even though the internal content ofthe message may show a _different_, and unrelated, "From" address. An SPF check of the _immediate_ sender does *NOT* break forwarded mail. Unless the forwarding process is _totally_ borken, that is. <grin>

> ... > Unfortunately, SiteFinder did not have such a destructive effect as we > had all wanted it to have. > ... that apparently depends on what you wanted and what you consider destructive. to me, as a domain holder under .COM, the damage was latent, coming in the form of "unacceptable business risk". as long as i know that my competitors would have to actually register "nearby" names in order to steal business from me, then i know (a) their costs are linear with my risk, and (b) i can find out what they're doing and perhaps even who they're paying to do it. in the presence of a wildcard and paid advertising, (a) no longer holds and there is no way to do (b). if sitefinder returns, i'd expect to have to find a new parent domain, who has no wildcard-like keyword system, just for risk management reasons. some domain holders might prefer to manage this risk by paying verisign extra money to get all the nearby keywords, but i'd consider this blackmail and i'd rebrand my offerings out of .COM and .NET, and i expect that many other domain holders would feel (and do) the same. ultimately i'd expect domain registration fees in wildcard-free TLDs to cost more than domain registration fees in wildcard-containing TLDs. also, to me, as a domain holder under .com who uses my domain for more than just a web site, i can't tolerate the lack of RCODE=3 when a "nearby" name is used by mistake. verisign promised not to use the connections for anything nefarious, but they are not a public-benefit corporation and if they thought that the best way to return value to their shareholders was to keyword-search e-mail that was sent to them by mistake, then they would be stupid NOT to do so. (this has been called a strong argument for all TLD registries to be required to be public-benefit corporations... foxes guarding chicken houses, and so on.) > So while SideFinder was not as destructive as we might have thought > or hoped, ... i wasn't hoping for anything in particular. but sitefinder was incredibly damaging, and its return would mark a sharp uptick in my risk management costs, and there's no way you could say it wasn't "destructive" based simply on your local network traffic analysis. simply put, i would have chosen a different TLD if i'd known that wildcard processing was going to occur, and i do not recognize verisign's right to unilaterally change the terms under which my domain's delegation data is served.

Except that, SPF records are as easy to setup for a spammer, as for you and I. If the above is a spammer, then SPF for foobar.com will list randomgibberish.comcast.net as an authorised sender. SPF will absolutely not have any effect on spam. And I say this merely as a disciple of Vixie - he thought of a form of SPF /years/ ago, and he knew /years/ ago it wouldnt do anything for Spam. The only difference between Vixie's MAIL-FROM MX records and SPF is the snake-oil: Vixie was honest in his claims for what it could do, the hype around SPF is not. regards, -- Paul Jakma paul(a)clubi.ie paul(a)jakma.org Key ID: 64A2FF6A Fortune: Reformatting Page.

"Intel calls for Internet overhaul"
by Paul Vixie 10 Sep '04

10 Sep '04

update SAN FRANCISCO--The Internet needs to be upgraded with a new layer of abilities that will deal with imminent problems of capacity, security and reliability, Intel Chief Technology Officer Pat Gelsinger said Thursday. Gelsinger pointed to PlanetLab, an experimental network that sits on top of the Internet, as a step in the right direction. Hewlett-Packard and Intel have begun work trying to commercialize the project, which was started in 2002, in order to overlay the Internet with intelligence and adaptability.

James, So this provider would select the path with the longer AS_PATH length and would advertise this one to its peers (if any). I believe then its for the others to decide if they want to take this route or not. Is my understanding correct? Thanks, Rohit Mtech Comp Sc.

Would it ever make sense for a provider to chose a longer AS PATH length BGP route against a shorter AS PATH length route? Yes many do - Prefer your customer routes via customer interfaces, over transit and peering interfaces. Higher LP over cust interfaces = more bits = more revenue. There is nothing wrong with this IMO, considering many of them who do this, also provide a community for customers to override this behaviour. Indiatimes Email now powered by APIC Advantage. Help!

Restoration after Hurricane Frances
by Sean Donelan 10 Sep '04

10 Sep '04

In Florida after Hurricane Frances: 17 fatalities attributed to the Hurricane and its affects. Wireless companies are reporting 95% service restoration statewide. Wireline companies have restored over half of the damaged lines statewide. Bellsouth: 385,000 and Sprint: 177,000 out of service. No figures available from other individual wireline companies. Adelphia reported it had restored 68% of its service. Comcast reports "significant progress." I heard of no reports of damage to any major co-location or Internet data center in Florida due to Hurricane Frances. NASA shutdown at least a portion of its computer networks at the Kennedy Space Center in advance of Hurricane Frances. Next up, Hurricane Ivan. The lower Florida Keys have evacuation orders for non-residents, RV's, boats and parks starting on September 10.
