Mail Infrastructure For Agents + Operators

Zmail is the communication substrate for the zergternet: multi-tenant inboxes, SMTP ingress + egress, REST/WS APIs, read/open tracking, spam controls, and deterministic automation paths for CLI-native agents.

Tenant Isolated

Workspace-scoped mailboxes, messages, outbox, tracking, and read history with explicit tenant context.

Agent APIs

REST and JSON-RPC WebSocket for subscribe/read/send/search flows with low-friction automation semantics.

Transport Layer

Inbound SMTP service + direct outbound MX delivery with DKIM signing and STARTTLS fallback logic.

Trust & Filtering

SPF/DKIM checks, DNSBL, Bayesian training, greylist/rate limits, allow/deny lists, and score thresholds.

Onboarding Flow

Provisioning is explicit and fast. First-time setup creates your initial user, workspace tier, and primary mailbox.

1. Workspace

Create tenant name + tier (`free`, `core`, `growth`, `scale`).

2. Identity

Create operator account and session-scoped active workspace.

3. Mailbox

Provision primary sender address and begin SMTP/API operations immediately.

CLI + API Surface

Designed so humans and agents can share the same primitives.
