Why I Love Catch-All Domains

1 Email Domain → Infinite Aliases

Instead of giving out me@example.com, I give:

• bob@example.com
• github@example.com
• xcompany2023@example.com

I know who I gave what. If something leaks, I know exactly who’s compromised.

Benefits

• Leak tracing — Know which vendor sold your info
• Spam isolation — Disable a single address, not the whole inbox
• Privacy — No centralized ID reused across the web
• Organized inbox — Filters by alias/tag are effortless

Sovereign Email

Paired with your own mail server, wildcard DNS, and a catch-all rule — you now own your identity layer.

I treat my inbox like a ledger —
every alias is a contract.

Tips

• Use wildcard MX + catch-all forwarding
• Self-host with tools like Mailu, Poste.io, or docker-mailserver
• Pair with wildcard SSL + nginx for webmail UI
