About

Practical guidance for careful operators.

Inbox Scaling documents the DNS and email-authentication tasks that are easy to describe but costly to get wrong.

The project focuses on clear operational reasoning: identify the authoritative system, preserve existing data, validate syntax, test both nameservers and keep a recovery path. Articles are written as durable reference material rather than vendor-specific shortcuts.

Editorial approach

We aim to separate facts from recommendations, explain tradeoffs and avoid promising outcomes that DNS alone cannot guarantee. Guidance is reviewed when infrastructure or standards change. Readers should still confirm provider-specific requirements before making production changes.

Administrative access

The accompanying YB NAME SERVER MANAGER is a private operational tool. It is separated from this public knowledge site so administrative records and credentials are never exposed to visitors.
