AWS SES Signature V4 : Can't find the request header in the log

I was using django-ses 0.8.5 as my email backend and I could see the request header in my application log, which belonged to signature V3.

Final headers: {'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8', 'User-Agent': 'Boto/2.49.0 Python/3.7.0 Linux/4.14.209-160.335.amzn2.x86_64', 'Date': 'Sun, 14 Feb 2021 20:32:57 GMT', 'X-Amzn-Authorization': 'AWS3-HTTPS AWSAccessKeyId=AKIEXAMPLEDTA,Algorithm=HmacSHA256,Signature=adWwLkredkdhfhfhhhdhxxxpxKa6o=', 'Content-Length': '44640', 'Host': 'email.us-east-1.amazonaws.com'}

according to the AWS announcement, they are moving to signature version 4. So I have updated Django-ses 0.8.5 to 1.0.3 latest.

these are my current versions django-ses == 1.0.3 boto3 == 1.17.7 botocore=1.20.7

But, After I update these, I can’t see the request header in my application logs to identify the signature version. could you please advise on this?

Glad I found this. Just upgraded django-ses to the latest to hopefully stop these nag emails from Amazon! [Action Required] Migrate to Signature Version 4 to continue using Amazon SES
