Emails Not Delivered to Apple Private Relay Addresses (Amazon SES)

If you're using Amazon SES and emails to @privaterelay.appleid.com are silently failing, the cause is almost certainly SES's account-level suppression list treating Apple relay DSN errors as hard bounces. Fix: Emails Not Delivered to Apple Private Relay Addresses (Amazon SES) If your app supports Sign in with Apple , some of your users will have a Hide My Email address — a relay address like abc123@privaterelay.appleid.com that forwards to their real inbox. These addresses are easy to break silently. Here's the symptom we ran into and exactly how we fixed it. The Symptom Transactional emails (alerts, welcome emails) worked fine for regular email addresses but never arrived for users who signed in with Apple. We were also receiving bounce notifications like this: Subject : Delivery Status Notification (Failure) An error occurred while trying to deliver the mail to the following recipients: prw8xms8tv@privaterelay.appleid.com Confusingly, some of these emails were being delivered — Apple's relay occasionally returns a DSN error even on successful delivery. But over time, delivery stopped entirely for affected addresses. Root Cause: SES Suppression List Amazon SES has an account-level suppression list . When a send results in a bounce (even a soft or misleading one), SES adds that address to the suppression list and silently drops all future sends to it — no error, no log entry from your code's perspective. Apple's private relay sometimes returns a non-standard response that SES interprets as a hard bounce. Once that happens: Send to Apple relay → Apple returns DSN error → SES logs as hard bounce → Address added to suppression list → Every future send silently dropped We found 9 Apple relay addresses on our suppression list, the oldest suppressed since September 2025 — meaning those users had missed months of emails. The Fix Step 1 — Remove suppressed Apple relay addresses In the AWS Console : Go to Amazon SES (make sure you're in the correct region) Left sidebar → Con

Appendix: Live System Output

Appendix: Live System Output — Real Pipeline in Production All output below was captured live from the running pipeline on 2026-03-08. These are not mock outputs — they come from actual AWS infrastructure and Kubernetes clusters.

EC2 Beginner Guide: Launch Your First AWS Instance

Introduction In my previous IAM article we learnt basics of IAM and how to create Users, Groups and attach Policies. You can refer here: https://dev.to/kadhamvj23/aws-identity-and-access-management-explained-for-beginners-cn7 After setting up secure access to our AWS account using IAM, the next question we mostly have is where do we actually run our application? The answer is Amazon EC2 - Elastic Cloud Compute. EC2 is one of the most widely used AWS services and understanding it well is essential for anyone starting their cloud journey. In this article we will cover what EC2 is, why it exists, the different types of instances, pricing models, Regions and availability Zones and finally hands-on walk through of creating your first EC2 instance. Breaking Down the Name -EC2 Let us understand what each word in the name actually means: Elastic --> In AWS you will notice many services have this prefix "Elastic". The reason is simple. Whenever AWS provides a service that can be scaled up or scaled down based on our needs, that service is called Elastic . With EC2 you can increase resources when traffic is high and decrease them when the traffic is low. So in simple terms EC2 = A virtual server on the cloud that you can resize anytime. Cloud: EC2 runs on AWS's public cloud infrastructure, meaning the servers are owned and managed by Amazon across the world. Compute: The word compute means you are asking AWS to provide you CPU, RAM and Disk - basically a virtual machine or server that can run your applications. How does EC2 actually work? When you request a Virtual server from AWS, here is what happens behind the scenes: You request a virtual machine on AWS ⬇️ request goes to a Hypervisor(a software layer sitting on top of physical servers that creates and manages VMs) ⬇️ Hypervisor creates your VM ⬇️ You get the access to your EC2 instance You never touch any physical hardware. AWS manages all of that for you. Why use EC2? Imagine your company wants to host an application. T

JaisCloud — A Free, Single-Binary AWS Emulator in Go

Why We Built JaisCloud — A Free, Single-Binary AWS Emulator in Go If you've ever tried to test AWS-dependent code locally, you've probably reached for LocalStack. It works — but it comes with baggage: Python runtime, Docker dependency, and the features most teams actually need locked behind a Pro subscription. JaisCloud is our answer to that problem. What is JaisCloud? JaisCloud is a free, open-source local AWS cloud emulator written entirely in Go. It implements the exact AWS wire protocols — Query/XML, JSON/Target, REST — so your existing SDK code points at JaisCloud and works unmodified. No shims, no proxy rewrites, no SDK patches. # Start it jaiscloud-aws start # Point your SDK at it export AWS_ENDPOINT_URL = http://localhost:4566 export AWS_ACCESS_KEY_ID = test export AWS_SECRET_ACCESS_KEY = test export AWS_REGION = us-east-1 # Your existing code works — no changes needed aws s3 mb s3://my-bucket aws sqs create-queue --queue-name my-queue The Problem With Existing Solutions JaisCloud LocalStack Community Moto Single static binary Yes No - Python + Docker No - Python library Zero runtime deps Yes No No Postgres persistence Yes Pro only No Real Spark/EMR execution Yes No No Apache Iceberg Yes No No Prometheus metrics Yes Pro only No State export / import Yes No No Deterministic time control Yes No No Written in Go Yes No No License Apache-2.0 Apache-2.0 Apache-2.0 Key Features Single Static Binary JaisCloud ships as a single Go binary per cloud. No Python, no Docker, no Node — just download and run. Works on laptop, CI runner, or Kubernetes pod. # Download and run — that is it ./jaiscloud-aws start # Or with Docker docker run --rm -p 4566:4566 rjaisval/jaiscloud-aws:latest Portable State Snapshots Export the complete emulator state — every resource, every account, every region to a single gzip tarball and restore it anywhere in milliseconds. # Capture a baseline jaiscloud-aws export -o baseline.tar.gz # Restore on a teammate's machine or CI runner jaiscloud-aws i

CISA Admin Leaked AWS GovCloud Keys on Github

Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files detailing how CISA builds, tests and deploys software internally, and that it represents one of the most egregious government data leaks in recent history.
