I'm using Sendy 5.2, but still am getting notified by Amazon that my campaigns "used Signature Version 3 to call Amazon SES APIs in the us-west-2 Region":
Your Signature Version 3 requests were identified to be using the following SES actions:
- APIs: GetSendQuota, SendRawEmail
My campaigns are being received and viewed. Is this something I should be concerned about?
You can ignore Amazon's email notices. If you're on the latest version of Sendy, it's using Amazon's Signature Version 4 API.
Sendy uses Amazon's Signature Version 4 API since November 2019. More info → https://sendy.co/forum/discussion/14863/amazon-ses-ends-support-for-039signature-v3039-update-sendy-to-the-latest-version#Item_1
