### Other information

CODE:

const relayName = "ests-fargate";
const cfnMailManagerRelay = new ses.CfnMailManagerRelay(this, this.version + "forward2relay", {
relayName: relayName,
authentication: { noAuthentication: {} },
serverName: "someendpoint.de",// this.nlb.loadBalancerDnsName,
serverPort: 2525 });

const cfnMailManagerRuleSet = new ses.CfnMailManagerRuleSet(this, this.version + 'CfnMailManagerRuleSet4Fargate', {
ruleSetName: this.version + 'CfnMailManagerRuleSet4Fargate',
rules: [
{
name: this.version + "processor",
actions: [
{
writeToS3: {
roleArn: 'arn:aws:iam::597414363306:role/checker',
s3Bucket: emailBucket.bucketName,
s3Prefix: 'tel-from-inbound'
},
relay: {
relay: cfnMailManagerRelay.attrRelayId
}
}
]
}
]
});

Reproduce the provided TypeScript example with AWS CDK 2.177.0, focusing on CfnMailManagerRuleSet actions that include relay. Inspect the SES CloudFormation rule-set validation path and compare it with the relay resource configuration. Done means a rule set containing the relay action synthesizes or validates without the reported Properties validation error.
