Hmm, are you sure?

 

[ec2-user@ip-10-0-0-50 ~]$ dig amazon.com <http://amazon.com>  txt +short|grep spf
"v=spf1 include:spf1.amazon.com <http://spf1.amazon.com>  include:spf2.amazon.com <http://spf2.amazon.com>

If anyone at Amazon is paying attention, you have duplicate spf1 records
for amazon.com <http://amazon.com> :

# dig -t TXT amazon.com <http://amazon.com>  | grep spf

It's causing mail deliverability issues, so users cannot reset their
password, or even get OTP codes reliably.

(I don't know where else to post, as whois/arin contacts aren't
responding, and I can't even imagine trying to go through other methods
of support...)
