test-config-tls-material.sh generates disposable GnuTLS material and covers CFG-09/CFG-10 generation, permissions, reuse, and unsafe-input cases.
web-direct-tls-smoke.sh covers the CFG-08 direct Web TLS 1.2/1.3 listener, security headers, plain-HTTP rejection, and a mismatched private key.
generate-protocol-test-config.py creates the disposable local protocol configuration used by sanitizer sessions.
protocol-smoke.py delivers through authenticated SMTP submission and reads the message through IMAP/POP over explicit and implicit TLS.
sanitizer-protocol-session.sh runs that protocol path under ASan/UBSan/LSan or TSan and validates clean process shutdown.
asan-protocol-session.sh and tsan-protocol-session.sh preserve the two explicit entry points used by the original release runs.
sieve-validate-no-lsan.sh is the narrow helper used by the ASan session; the Sieve validator remains leak-tested directly by CTest.
cpack-stage-smoke.sh checks imports and required executables from an extracted CPack staging tree in a private mount namespace.
debian-source-probe.sh and debian-libspf2-package-build.sh preserve the disposable Debian container probes used before the complete bundle builder was available.
setup-wizard-defaults.py, config-tui-edit.py, legacy-config-install.py, protocol-diagnostics.py, and store-diagnostics.py preserve the remaining interactive and diagnostic bring-up tests. Destructive live helpers require an explicit opt-in environment variable.
mail-dns-live-check.py logs in through the real Web and IMAPS interfaces and verifies that setup produced both an actionable SPF/DKIM/DMARC task and a forwardable administrator message without private-key material.
dkim-material-check.py compares a real OpenDKIM-generated RSA-2048 key with Bongo's GnuTLS-derived public value, imports it, checks permissions and DNS output, then verifies byte-identical reuse.
manager-lifecycle-check.sh exercises systemd reload/restart/stop/start, one agent crash, and an unclean manager death which leaves a stale PID file. It requires explicit live-test opt-in and restores an active service on exit.
agent-privilege-check.sh verifies the live manager/agent process tree, real/effective/saved UID and GID tuples, supplementary groups, and inherited, permitted, effective, and ambient capabilities.

The complete mapping from the original one-off /tmp names to maintained scripts is recorded in tmp-script-map.md.

Every script which creates credentials requires disposable values through the environment; no test password or private key is stored in Git. For example:

export BONGO_TEST_PASSWORD='a-disposable-password-of-at-least-12-characters'
export BONGO_TEST_ROOT=/tmp/bongo-0.7-r1-asan-root/usr
export BONGO_SANITIZER=asan
unshare --user --map-root-user --net \
  ./contrib/testing/sanitizer-protocol-session.sh

The Debian source probes and package-build commands used by BLD-14/BLD-15 are consolidated in contrib/debian/build-trixie-bundle.sh; they are not maintained as duplicate container-only snippets here.

Cyrus IMAP, POP3, and LMTP

Install net-mail/cyrus-imapd, then start the disposable fixture as root:

sudo ./contrib/testing/cyrus-fixture.py start

It creates no files outside /tmp/bongo-cyrus-fixture and listens on:

IMAP: 127.0.0.1:18143
POP3: 127.0.0.1:18110
LMTP: 127.0.0.1:18024

The source mailboxes form a multi-account-per-user matrix:

Bongo owner	Cyrus source account	Protocol	Bongo destination
`test1`	`test1-pop@cyrus.bongo.test`	POP3	`INBOX`
`test1`	`test1-imap@cyrus.bongo.test`	IMAP	`Cyrus IMAP`
`test2`	`test2-pop@cyrus.bongo.test`	POP3	`INBOX`
`test2`	`test2-imap@cyrus.bongo.test`	IMAP	`Cyrus IMAP`

All source accounts use the test-only password BongoCollector-Test-2026. Insert a complete RFC 5322 message through Cyrus' real LMTP delivery path:

sudo ./contrib/testing/cyrus-fixture.py inject message.eml

Seed three different messages in each source mailbox and exercise Bongo's real Collector POP3 and IMAP transport implementation:

./contrib/testing/cyrus-fixture.py verify-collector \
  --probe ./build/src/agents/collector/collector-remote-transport-probe \
  --count 3

The probe lists and fetches every message, checks its fixture marker, deletes it through the selected protocol, and verifies that every Cyrus source mailbox is empty. A live end-to-end run creates all four Bongo external-account records. This proves that accounts, remote UID/UIDL values, retry state and deletion state remain scoped by account ID even when one Bongo user owns multiple sources. All four use after_import, so Cyrus deletion happens only after the Bongo Queue has durably accepted and committed the complete message. From that point the normal scanner, rules, quota, and Store delivery pipeline owns it.

The fixture can also seed deterministic scanner and quota cases. All ports remain loopback-only and the flood is deliberately bounded:

sudo ./contrib/testing/cyrus-fixture.py seed --profile gtube --count 1
sudo ./contrib/testing/cyrus-fixture.py seed --profile eicar --count 1
sudo ./contrib/testing/cyrus-fixture.py seed --profile flood --count 32 \
  --message-size 131072
sudo ./contrib/testing/cyrus-fixture.py seed-suite

gtube contains SpamAssassin's standard GTUBE string. eicar creates the harmless standard EICAR attachment at runtime; the complete signature is kept out of the Git checkout to avoid host antivirus false alarms. seed-suite places three normal messages, one GTUBE message, one EICAR message, and 32 128-KiB flood messages in every source mailbox (148 messages total). Set a small quota on disposable Bongo users before collection, then restore it after the test. The test passes only when clean messages are imported, scanner policy is applied, quota cannot be exceeded, and a message rejected before a durable import remains retrievable from Cyrus.

The same LMTP listener is the forwarding target for the exact transport-domain mapping below. This accepts *@cyrus.bongo.test without making the test domain a local Bongo domain:

"lmtp_transports": ["cyrus.bongo.test=127.0.0.1:18024"]

Cyrus lmtpd is pre-authorized only on this loopback-only fixture listener. That matches a trusted local MTA-to-store LMTP hop and must not be copied to a network-exposed Cyrus listener.

The generated short-lived test CA at /tmp/bongo-cyrus-fixture/tls/ca.crt is the fixture trust anchor. Set BONGO_COLLECTOR_CAINFO to that path for the Collector process during this test; normal installations continue to use the operating-system trust store. The packaged bongo.service uses PrivateTmp=true, so a live systemd test must make the fixture visible inside that service namespace. A runtime-only drop-in can bind precisely this fixture read-only:

[Service]
BindReadOnlyPaths=/tmp/bongo-cyrus-fixture

Install it with systemctl edit --runtime bongo.service, restart Bongo, and set the Collector ca_file to the path above. Do not weaken certificate or host-name verification for the test.

After a live collection cycle, show the source-mailbox counts with:

./contrib/testing/cyrus-fixture.py mailbox-status

Stop or remove all fixture state with:

sudo ./contrib/testing/cyrus-fixture.py stop
sudo ./contrib/testing/cyrus-fixture.py reset

Outbound SMTP capture

Use net-mail/xeams-devnullsmtp-bin from the Bongo Gentoo overlay:

xeams-devnullsmtp -p 2526 -d bongo.test -s /tmp/bongo-devnull-mail

Configure 127.0.0.1:2526 as Bongo's relay host before testing any non-local recipient. Xeams DevNullSMTP has no listen-address option, so isolate it with a firewall or network namespace; do not expose it on a production network.

HAProxy and PROXY v2

haproxy-bongo-test.cfg exposes loopback-only high ports and forwards every connection to the corresponding normal Bongo listener with a PROXY v2 header. Before starting it, temporarily enable proxy_protocol_enabled and set proxy_protocol_networks to ["127.0.0.1/32"] in the smtp, imap, pop3, and sieve documents. Never trust an unbounded network for PROXY headers.

Validate and run the fixture in the foreground:

haproxy -c -f contrib/testing/haproxy-bongo-test.cfg
haproxy -db -f contrib/testing/haproxy-bongo-test.cfg

The test listeners are SMTP 11025, submission 11587, submissions 11465, IMAP 11143, IMAPS 11993, POP3 11110, POP3S 11995, and ManageSieve 14190. Exercise real protocol greetings, capabilities, authentication, and TLS handshakes through these ports, then restore the original Bongo documents.
