SPF Fails IP Address Not Permitted Sender

Question

My emails SPF are failing because 209.222.82.148 is not a designated sender for my subdomain used in the MAILFROM setup.  
  
My TXT Record for the MAILFROM setup is:  
v=spf1 include:amazonses.com -all  
I have tried ~all as well, but I wouldn't expect that to work.  
  
I am getting this TXT record when looking at amazonses.com for the allowed IP addresses. This IP address does not seem to fit any of these ranges:  
v=spf1 ip4:199.255.192.0/22 ip4:199.127.232.0/22 ip4:54.240.0.0/18 ip4:69.169.224.0/20 ip4:76.223.180.0/23 ip4:76.223.188.0/24 ip4:76.223.189.0/24 ip4:76.223.190.0/24 -all  
  
What is causing the sender IP to be different than those allowed from amazonses.com? The only thing that I can imagine it being is that my SES is currently under sandbox access.

Thank you, that made me realize I needed to add the barracuda SPF domain for mail for subdomain's SPF record  
  
Record  
TXT v=spf1 include:spf.ess.barracudanetworks.com include:amazonses.com -all

Hi,   
  
Sandbox mode has no relation. If you were sending to a non verified recipient in sandbox mode, it will give you an address not verified error.   
  
Regarding SPF - All mechanisms may specify qualifiers for how to handle a match:  
+ for pass  
- for fail  
~ for soft fail  
? for neutral  
  
Now checking the IP address "209.222.82.148" that you have mentioned looks to be from Barracuda email security service. Is your email being relayed via some other SMTP?  
  
$ dig -x 209.222.82.148 +short  
mail.ess.barracuda.com.  
  
Can you please provide the complete header details from the receiving side?   
  
Regards,  
Gaurav @ AWS
