Domains

A domain is a claimed, postmaster-authorized mail suffix — like sithbit.com — that a mailbox references so that MX servers know how to route mail to it over SMTP. Domains are registered and administered on-chain: someone must claim a domain and have the postmaster authorize it before mailboxes on that domain can send or receive mail through the normal MX/SMTP path.

Looking up a domain

sithbit domain get <domain>

This is always available — unlike the admin subcommands below, it needs no special CLI feature. For example:

sithbit domain get sithbit.com

Note: domain create, domain transfer, and domain deactivate require the CLI’s domain feature (enabled by default) and always require the postmaster’s signature — domain administration is not something an ordinary mailbox owner can do unilaterally.

Deactivating a domain (see Deactivate a domain) blocks sending and deleting mail for mailboxes that reference it, and also blocks creating or updating a mailbox to reference it: a mailbox’s domain must be a registered, active domain account (or no domain at all), so deactivation locks a domain down from new registrations too.
