Adds application accounts bound to domains: a SASL login/password in sasldb2, a per-application address mode (wildcard @domain or an explicit list), and matching smtpd_sender_login_maps bindings — with create, list, edit-mode, delete and password regeneration (spec 4.1, 5.1, 7.2.5-9). Generated passwords are shown exactly once and never stored in plaintext (7.6.1). - internal/store/applications.go: transactional CRUD; globally unique login; ListBindings (address->login) as the map source; logins-by- domain for pre-cascade SASL cleanup. - internal/app: saslpasswd2 wrapper (password via stdin, login as a whitelisted argv element, no shell — 7.6.3); strong base64url password; address validation that enforces domain ownership before any config write (7.6.2); service orchestrating store + sasldb2 + map with full rollback on partial failure. - internal/postfix: sender_login_maps regenerated as a pure function of the registry (many-to-one logins merged per address), atomic write, injection backstop (7.6.4). - Postfix reload, corrected: `postfix start-fg` forks a separate master, so signalling the supervised process never reaches it. Reload now runs the canonical `postfix reload` via a one-shot supervisord program the unprivileged panel triggers over the group control socket. Verified in mail.log. - domain.Service.Delete purges the domain's SASL accounts, then cascades, then rebuilds the sender map and reloads; manual reload now covers both OpenDKIM and Postfix. - web: application management in the domain page, one-time credential shown inline; postfix joins the selfpost group and entrypoint normalises /data/sasl and /data/postfix (setgid, group-readable) with self-heal. Verified on the dev server: gofmt/vet/test green, image builds, and a container e2e covers the full application lifecycle, domain-delete cascade, restart persistence, and a real postfix reload.
