Override the envelope MAIL FROM with a domain we own when talking to the
upstream relay. SPF passes at the recipient; the attacker's From: header
inside the message body is untouched so they see their own address in their
inbox and believe the relay is real.
First SMTP_PROBE_LIMIT messages per source IP are forwarded via a real
upstream relay (SMTP_UPSTREAM_HOST/PORT/USER/PASS) so the attacker's
test email actually lands in their inbox. All subsequent messages from
the same IP get 250 Ok but only hit the quarantine — campaign content
captured, nothing delivered.
- Declarative config_schema on RDP, Telnet, MySQL, Redis, SMTP, SMTP_Relay
matching the keys each service already reads at compose time.
- TODO marker on the 19 services that accept service_cfg but never read it,
so future contributors know where to plug schemas in.
- Wizard base64-wraps all textarea values at INI emit (DeckyFleet
buildIni); validate_cfg detects the b64: sentinel and decodes back to
UTF-8. Plain raw strings still pass through for direct API submitters.
- HTTPS image entrypoint accepts PEM content or path in TLS_CERT/TLS_KEY:
detects a BEGIN header, writes content to /opt/tls/, and re-exports
the on-disk path so server.py keeps reading paths.
- Tests cover schema/compose alignment for each new service plus
textarea base64 round-trip (incl. UTF-8) and HTTPS PEM end-to-end.
- decnet/services/smtp_relay.py: open relay variant of smtp, same template
with SMTP_OPEN_RELAY=1 baked into the environment
- tests/service_testing/__init__.py: init so pytest discovers the subdirectory
