Hi
I was working with Sendy from the version 4 with Amazon SES and recently bought the version 6, in the release 6.0.2 the Amazon SES does not work, I deleted the IAM user and created a new one, added permissions for both SNSfull and SESfull, re-added the domain and emails in SES until the verified status appears. I also make some tests in AWS and it is working fine. My sending limit is 200,000. Everything seems ok, but I always received the status error Error: SignatureDoesNotMatch in Sendy. I have CentOS 7 on linode
