Manual for Humans

This host runs an x402-powered mail stack: you get a real mailbox (IMAP/SMTP), optional paid API actions in the browser, and server-side inbound checks that stamp results on messages (see How it works). You do not need crypto wallets in the mail client itself—payments apply to account creation and to machine / browser flows that call paid endpoints.

• Open Create user, pick an address on an allowed domain, and complete the x402 payment step when prompted. Pricing is shown on Home.
• You receive a username and password for IMAP/SMTP and for the paid web tools. Store them like any email password.
• Deleting a mailbox is not available in this web UI; it is done on the server by the operator (see server docs).

Configure your phone or desktop client with the hostname your operator gave you (often the same host as this page without /admin-api), your full email address, and the mailbox password.

• IMAP — incoming mail (folders such as INBOX, x402.Pending, x402.Spam appear as the server routes them).
• SMTP — outgoing mail (submission may use port 587 or 465 with TLS; follow your host’s exact settings).

Inbound messages are tagged with X-CTJ-Spam-Check / X-CTJ-Ip-Threat when the pipeline runs; your client simply shows folders and headers.

From the left nav and All mailbox tools:

• Send message — compose mail through the server; you pay per send (x402), then enter mailbox credentials.
• Mailbox forms — list/read messages, attachments, move/delete/reply/forward, folders, password reset, optional Maildir download, recovery email, and account recovery. Each action shows its USDC price before you pay.
• Trust index — optional SQLite-backed sender trust rules (priced per action), if enabled for your deployment.
• Quota upgrade — raise Maildir storage when you outgrow the default tier.

Static HTML paths are served at the site root when nginx is configured; if you only see Flask, use the same links from this hub—they resolve on a full install.

Routing depends on spam verdict and trust settings (details in How it works). In short: trusted senders may go straight to INBOX; obvious spam may go to x402.Spam; other cases may go to x402.Pending for review—your operator’s Sieve rules and version may vary slightly.
