Manual for Humans

This host runs an x402-powered mail stack: real mailboxes (IMAP/SMTP), optional paid browser tools, and inbound checks that stamp X-CTJ-Spam-Check / X-CTJ-Ip-Threat on messages (see How it works). Crypto wallets are for paid web/API steps, not for reading mail in a normal client.

• Open Create user, pick an address on an allowed domain, and complete the x402 payment step when prompted. Live prices: Home and https://mail.cusethejuice.com/admin-api/ui/config.
• Some domains require a domain administrator password at signup (registered custom domains and most non-default hosted domains). Use the password you set when the domain was registered.
• You receive a mailbox username and password for IMAP/SMTP and for paid web tools. Store them like any email password.
• Optional authenticator MFA (TOTP) can be enabled via the machine API or web flows; when enabled, paid tools ask for a six-digit code in addition to your password.
• Deleting a mailbox is not available in this web UI.

• Register domain — annual x402 subscription to host mail on a domain you control; set administrator password, external recovery email, and optional recovery PIN.
• Domain admin — sign in (x402 per session when configured), manage mailboxes on that domain, renew, view MX / SPF / DKIM / DMARC DNS hints, change recovery email, reset password with PIN, and optional login MFA for administrator sign-in.
• Forgot administrator password — on the Domain admin login page, pay USDC per reset attempt, then use your recovery PIN or request a one-time code to the recovery email on file.

Configure your client with this site’s mail hostname (often the same host without /admin-api), your full email address, and mailbox password.

• IMAP — folders such as INBOX, x402.Pending, and x402.Spam as the server routes them.
• SMTP — submission (often port 587 or 465 with TLS).

From the left nav and All mailbox tools:

• Send message — compose → x402 → mailbox password (and MFA code if enabled).
• Mailbox forms — list, search, read, attachments, quota, move/delete/reply/forward, folders, password reset, mailbox download, recovery email, account recovery. Each action shows its USDC price before payment.
• Trust index — optional sender-trust rules (priced per action) when enabled.
• Quota upgrade — paid storage tiers (100 MB / 500 MB / 1 GB).

The same flows are also linked from All mailbox tools in this app.

• Recovery email — while you can sign in, register an external address (not hosted here) for forgot-password codes.
• Account recovery — if you cannot sign in, use the recovery flows on /machine-mail.html (request code → pay → email; complete with code + new password).
• Mailbox MFA — when enabled, every paid tool that checks your password also needs a six-digit authenticator code.

Routing depends on spam verdict and trust (see How it works). Trusted senders may reach INBOX; many non-trusted stamped outcomes go to x402.Pending for review; strong spam may go to x402.Spam.
