Sender Address Verification: Solving the Spam Crisis

• Comment posted Aug 20, 2004 2:40 pm PDT — by Chris Linfoot
  With SAV, email is accepted and a request for verification is sent back to the purported originator of that email. Given that most spam and virtually all viruses spoof the sender address this can mean that an innocent bystander is…

  I have to say I am just as disappointed as Brett to see this article here at CircleID of all places. I have not a lot to add to Brett's comment save to note that most of the attempts to…

Sender ID: A Tale of Open Standards and Corporate Greed? - Part I

• Comment posted Sep 03, 2004 7:19 am PDT — by Chris Linfoot
  Agree entirely - and the first step in my opinion is for domain owners to publish SPF or Sender ID (or both) for all their domains, which is exactly what we are doing here. Just to be clear though -…

  Interesting article. Thanks. Just one minor correction and one comment, if I may… First - that minor correction: RFC821 and RFC822 were in fact superseded by two new standards track RFCs conveniently numbered RFC2821 and RFC2822 in early 2001. As…

A Network by Any Other Name

  Or is it "Emailed"? Just kidding. Yes, I agree. I always use uppercase when writing about the Internet for precisely the reasons you so eloquently describe and I will continue to do so regardless of what others choose to do.

Why DomainKeys is Broken

• Comment posted Oct 28, 2004 12:26 pm PDT — by Chris Linfoot
  Perhaps my mistake was in the title of this piece. DomainKeys is not broken - indeed the theoretical concept is well founded. However there exist many practical obstacles to widespread adoption, one of which I have illustrated. The issue here…

  I agree. I originally wrote this piece for an IBM/Lotus Notes/Domino user audience and, clearly, there are issues that need to be addressed to make DomainKeys viable for such users. I suspect the issue is more widespread however (incorporating many…

Does CAN-SPAM Really Matter?

• Comment posted Mar 01, 2005 8:32 pm PST — by Chris Linfoot
  Just to clarify, the volume of spam we have from AOL is too low to be susceptible to any meaningful statistical analysis, but it has grown recently with 4 sightings in the past 24 hours. One of those was a…

  Some comments if I may: 1 - CAN-SPAM is an American law. Here in the EU, we see a substantial amount of spam citing CAN-SPAM compliance somewhere in a footnote. This tends to suggest a couple of thoughts: a) if…

Sitefinder Writ Small

• Comment posted Sep 15, 2005 8:23 am PDT — by Chris Linfoot
  Actually the main issue for me is the second one (fat finger mail addressing) though I don't like to be reminded of Sitefinder. Fat finger addressing is sadly a fairly regular occurrence and it can lead to delays in communication…

In Praise of OpenDNS and a Wii Factoid

• Comment posted Apr 07, 2008 8:16 am PDT — by Chris Linfoot
  > where does this “Wii Factoid” come from Jeroen, the factoid I describe here is that the Wii does AAAA DNS lookups. This is self evidently true. As to why? Ask Nintendo. They have some very clever people working there…

Trust in Email Begins with Authentication

• Comment posted Apr 03, 2008 12:13 pm PDT — by Chris Linfoot
  I have been mulling this idea for a while now.  This may seem elitist, but what if, to run a mail server you had to pay $500, for the privilege of registering their server with a trust authority Public Key…

  Thanks Suresh. Didn't know that. Do now.

Why New TLDs Don't Matter

  I guess I should have posted this blog post of mine here at CircleID…
