SignatureDoesNotMatch, The request signature we calculated does not match the signature you provided

I have looked at other questions on SO, all of them don't have SES and Java as part of their question.

Exception

Exception in thread "main" com.amazonaws.AmazonServiceException: Status Code: 403, AWS Service: AmazonSimpleEmailService, AWS Request ID: 6828fb27-8972-11e3-9700-b705133266ce, AWS Error Code: SignatureDoesNotMatch, AWS Error Message: The request signature we calculated does not match the signature you provided.

                + " to verify it");
        System.exit(0);
    }
}

SES Setup

  1. Added myproductdomain.com to Domains.
  2. Added [email protected] to Email Addresses.

AwsCredentials.properties

  1. For secretKey="aws website login password"
  2. For accesskey="https://console.aws.amazon.com/iam/home#users, security credentials, for ses-smtp-user.some_number, access key"

I am trying out the "hello world" of the SES from the eclipse plugin. Should have worked right out of the box.

I believe the problem is that you uses is an "ses-smtp-user.some_number". You see, with SES, there are two ways to send emails.

  • using web service (AmazonSimpleEmailServiceClient)
  • using SMTP

The user that was created was for smtp, ses-smtp-user.some_number. You are using that credential for a web service call.

My suggestion is to create a normal user (not from the SES screen), and assign SES permissions. Do note that the newly created credentials won't work with SMTP now.

If you want a credential that works with both, SMTP and web service, you may want to read up on this: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/smtp-credentials.html#smtp-credentials-convert
