What were you trying to accomplish?
Validate SQS. Was presented a rule violation that said I needed a RedrivePolicy. Added the policy and DLQ, was presented with the same error against the DLQ.

Expected Behavior

If a SQS queue is already configured as a DLQ for another SQS queue, don't run the rule on the DLQ.

Current Behavior

I have this code

  SagaQueue:
    Type: AWS::SQS::Queue

you run the serverless rules and you rightly get

ES6000 SQS Queue SagaQueue should have a RedrivePolicy property configured.
template.yaml:314:3

So I add

SagaQueue:
  Type: AWS::SQS::Queue
  Properties:
    RedrivePolicy: 
      deadLetterTargetArn: !GetAtt SagaDeadLetterQueue.Arn
      maxReceiveCount: 5
SagaDeadLetterQueue:
  Type: AWS::SQS::Queue

but now I get

ES6000 SQS Queue SagaDeadLetterQueue should have a RedrivePolicy property configured.
template.yaml:326:3

It will be a never ending story.

Possible Solution

Can this be fixed so it detects a DLQ but not run the redrive rule on that?
