Hmm, are you sure?

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

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

# dig -t TXT amazon.com | grep spf
amazon.com.             281     IN      TXT     "spf2.0/pra include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all"
amazon.com.             281     IN      TXT     "v=spf1 include: amazon.com include:spf1.amazon.com include:spf2.amazon.com include:amazonses.com -all"

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...)
