Skrzynka
Self-hosted multi-mailbox inbox and reply service
Skrzynka synchronizes messages from multiple IMAP mailboxes into one local durable inbox and sends each reply through the same mailbox identity, resolving credentials from Skarbiec only at final use.
Product contract
- Skrzynka gives one local operator a unified durable view of messages from multiple mailboxes while preserving the receiving mailbox identity.
- A successful receive means a provider message was persisted locally; a successful reply means the configured SMTP server accepted it.
- Skarbiec owns credential encryption, recovery, rotation, and revocation while Skrzynka stores exact item references, normalized messages, sync cursors, and reply evidence.
- The current contract is single-operator and loopback-only; it does not mutate provider folders, flags, retention, or deletion state.
