I like option 4. But only for the first year, after that assume "-all".
But "-all" only if IETF accepts spf as a standard.
During the first year, send a warning back to the sender about the grace
period?
Option 2 is good also. But how high do you climb? All the way to "."?
Maybe both! Climb the tree, if nothing found assume "a/24 mx/24 ptr -all".
Well, you'd need some stopper. A special record that says 'if you are checking
for a record because you didn't find one on one of the lower domains, do not
look any further, i or my ancestors do not publish for lower domains'.
Perhaps this should be a modifier 'recurse=no' or something like that..
But as the spec is today... I should use option 3?
It is your only option in the current state of affairs, correct.
