Hello,
FYI, we have updated our SPF syntax validator and added an SPF
evaluation check service to our website.
SPF Syntax Validator: http://www.vamsoft.com/orf/spft/spfvalidator.asp
SPF Checker: http://www.vamsoft.com/orf/spft/spfcheck.asp
Both services are based on the original SPF Classic draft
(http://www.libspf.org/files/spf-draft-200405.txt) and the Checker
provides detailed log of the evaluation, so it may be useful for
troubleshooting purposes.
I thought that you may be interested (and hope that you will tell me
if you find any problems :) Note that the above URLs are temporary,
the final services will be published without /spft.
Peter
