[spf-discuss] spf in dns survey

2007-12-12 15:14:44
Hi all

Thought you might be interested in this from Cricket Liu's
executive summary of "The 2007 DNS Survey, performed by The
Measurement Factory and commissioned by Infoblox" ...

| Other Interesting Findings:  Significant Interest in Email Authentication 
|  
| Support for SPF was a highlight, more than doubling from about 5%
| of zones sampled to 12.6%. Clearly SPF has significant momentum.   
|  
| Implications:  Thanks to the network effect, the more zones that use
| SPF, the greater the value in implementing SPF (e.g., the larger the
| percentage of email you can verify).  SPF’s popularity has the
| chance to snowball.  I believe SPF’s success also bodes well for
| the prospects of DKIM, which like SPF uses DNS to store email
| authentication information.
