set Google Apps SPF record in Amazon AWS Route 53
Solution 1:
I had to wrap my SPF record in quotation marks for it to work.
"v=spf1 include:_spf.google.com ~all"
Solution 2:
It's a new feature for the console. Chances are it's the console part that is rejecting the 'invalid' characters, rather than the underlying system.
I'd try setting it with one of the many tools available for configuring Route 53 and if that doesn't work, contact Amazon
