Hello.
I understand your goal: to generate temporary email addresses for each user, receive and securely link incoming messages with the reserved user, verify the authenticity of the sender against a pre-approved list, and scale to hundreds of thousands of temporary addresses with automatic TTL deletion.
My plan is to implement temporary addresses using namespaces/subaddressing for each user (or unique mailbox tokens), route incoming mail through a lightweight SMTP pipeline (Postfix/Haraka or a managed inbound mail provider with webhooks) to workers that analyze/store messages and resources in object storage and a relational database, and provide a simple API/webhook for the service to consume the results.
To ensure sender authenticity, I will check SPF/DKIM/DMARC (and ARC where possible), verify DKIM signatures and reverse DNS/TLS handshakes, check the reputation of the outgoing IP address and SMTP conversion (and optionally S/MIME/PGP signatures), and only accept those messages that pass these checks or come from a predefined whitelist — all checks and raw evidence will be logged in an audit log (with a hash signature) to ensure non-repudiation.

The solution will include scalable queues, GC for TTL-based deletion, monitoring/notifications, and complete documentation + deployment scripts (Docker/K8s), so you will receive a ready-to-use high-performance system that can be integrated into your service.

Good day! 👋

I carefully read the task description — it is essentially a service for temporary email addresses linked to the user, verifying the authenticity of the sender, and further integration into your product. This topic is very close to me: I have worked with integrations of email services, webhooks, SPF/DKIM/DMARC verification, and the design of systems that handle a large volume of emails.

I want to propose not just something that works, but a well-thought-out module that will safely live in production and scale properly.

I have prepared detailed questions for you about the project, work stages, and solution architecture in Notion format: https://www.notion.so/email-2a1ea80ec59480e9a8a9d6a6ca8f38d9?source=copy_link. Due to the large amount of information, I hope this will be more convenient; I wanted to include all the details.

Attention!
If I indicated in the total bid "1111" or "777", it means that I need more information to assess the project (also, deadlines may vary depending on the scope).
