Think China Is the Highest Spamming Country? Think Again

• Comment posted Jul 19, 2009 11:49 pm PDT — by Colin Dijkgraaf
  In my opinion statistics about spam received at a single or even a small number of domains on the internet is too narrow a sample to reach any conclussions about world wide spam. To get more accurate measures you need…

IP Address Intelligence Burdening Content Providers with Regional Laws?

• Comment posted Feb 07, 2007 3:48 am PST — by Colin Dijkgraaf
  Addressing the question "does it now make sense to put content sites to the burden of complying with the laws applicable to the people/machines they know are visiting them?" No, even if you could identify with 100% accuracy the geographical…

Internet Governance: An Antispam Perspective

• Comment posted Feb 16, 2006 6:44 am PST — by Colin Dijkgraaf
  Nobody is claiming it is easy, and yes, just replacing SMTP with a better standard won't be the final solution to getting rid of SPAM.  In fact I believe that there will always be SPAM, and there is no final…

  Both whitelisting and blacklisting have the same flaw at the moment. They both have a problem establishing the identity of the sender.  Whitelisting an e-mail address is all well and good, until a friend of yours has his machine taken…

Urban Identity by City Top-Level Domains

• Comment posted Jan 04, 2006 7:37 pm PST — by Colin Dijkgraaf
  Why do you even need TLD's for this?  As a city is in a particular country, why not just us the domain city.cTLD and allow people the have sub domains of that?  Yes there might be some cases where these…

How to Stop Spam

  Here is another approach to stopping spammers. Project Honeypot targets those that use e-mail harvesters to get e-mail addresses from your web pages. I've signed up and added a honeypot to my web site. You can learn more and sign…

  Daniel, unless your ISP validates the From and/or Sender address on outgoing e-mail (which most ISP's don't do as yet), you can quite happily point your SMTP (port 25) to your internet provider, while pointing your POP (port 110) to…

  I agree that just blocking or redirecting outgoing port 25 and ignoring compromissed machines isn't all the ISP should do.  But if they do block 25, then the ISP doesn't have to spend as much resources on having to analyse…

  I quite agree with Carl.  In addition to this, responsible ISP's also scan outgoing mail for viruses (not just incoming), this will reduce the number of machines getting infected and being turned into zombies.  Responsible ISP's will also have terms…

Third-Level Domain Name Hijacking

• Comment posted Dec 09, 2004 12:15 am PST — by Colin Dijkgraaf
  Hardly a new thing, I experience this over 2 years ago. I had a third level domain off start.at (NAME.start.at or start.at/NAME) I won't mention what NAME was (at it now goes to a porn site and I don't want…

Sender Address Verification: Solving the Spam Crisis

• Comment posted Jul 27, 2004 11:40 pm PDT — by Colin Dijkgraaf
  Yes, but "Verification" is not the same as "Authentication".  I'm all for Authentication, but Verification will not work, and just cause more issues that it solves.

  Sorry, again a flawed technique. SPAMmers will just change tactics, and when they harvest e-mail addresses from compromised machines, they will make sure they capture that users e-mail address as well, so as to have a legitimate FROM address, that…

Email Address Forgery

• Comment posted Jun 18, 2004 1:57 am PDT — by Colin Dijkgraaf
  Yes I agree it is complex. Just validating the domain is not sufficient, the whole e-mail address needs to be validated, and not only that it is a valid e-mail address, but that the person trying to use that e-mail…

Can Technology Can Spam?

• Comment posted Jun 03, 2004 1:53 am PDT — by Colin Dijkgraaf
  Most of the techniques to combat SPAM are focusing on filtering it at the receiving end, even with the best filtering techniques some will still get through, and it adds an extra processing overhead to the receiving servers.  SPAM needs…
