Inventories and their limits
The transparency page provides the website SBOM and a separate package inventory for the Debian host. The website inventory records the published components and artifacts; the host inventory records installed operating-system packages at its observation time.
These inventories do not reconstruct every embedded library, build tool or original software dependency. A package list also does not show that every known vulnerability has been fixed. Host findings require a separate assessment against the relevant Debian and vendor information.
Mail platform: lab and plans
The following components belong to development of the mail platform. They are not running as customer services on the production website host.
| Software | Intended purpose | Status |
|---|---|---|
| Postfix | SMTP mail transport | in the development lab |
| Dovecot | IMAP/POP3 mailboxes and encryption | in the development lab |
| Rspamd | spam filtering | in the development lab |
| PostgreSQL | account database | in the development lab |
| Knot DNS | self-hosted DNS | planned |
| Prometheus and Grafana | monitoring | planned |
Planned publications
Webmail, future apps, encryption and key processing are intended to be published under free licenses. This also covers Domain Autopilot checks, the manifest generator and our changes to the open-source software we use. Public sources and review results will be linked here when available.
For future spam and fraud detection rules, we still need to decide what can be disclosed without making them easier to evade.
