External mail accounts
External IMAP and POP3 credentials are stored in
external-accounts.sqlite. Credential values are encrypted with AES-256-GCM;
the per-installation master key is stored separately as
external-accounts.key in Bongo's DBF directory. Both files are restricted to
the Bongo service account.
Back up the database and master key together. A database backup without the matching key cannot decrypt external-account credentials. Do not copy the key to another installation unless the associated database is moved as well.
The collector verifies TLS certificates and host names by default. Provider passwords are never included in URLs or log messages. Existing plaintext credential records from early 0.7 development versions are encrypted automatically the next time they are read.
For an internal provider signed by a private certificate authority, set
ca_file in /etc/bongo/config.d/collector to the absolute path of a PEM CA
bundle and run bongo-admin config sync. Certificate and host-name
verification remain enabled. Prefer installing a site-wide CA through the
operating system trust store when possible. BONGO_COLLECTOR_CAINFO remains
available as a test-only environment override.
Remote deletion policies are never, after_import, and after_days.
Messages are recorded as imported only after Bongo's durable Queue accepts and
commits the complete message. The normal antivirus, antispam, Sieve/rules,
quota, and Store delivery pipeline owns it from that point onward. A failed
remote deletion does not cause the message to be delivered again; the
collector retries the deletion during a later poll.
