Production mail platform updated and independently validated
The SCComp mail platform is now fully patched on the current stable Mailcow release, with refreshed security components and a successful independent delivery-authentication test.
We completed a controlled production update of the SCComp mail platform after creating a full data and configuration backup. Mailcow, Postfix, Rspamd, SOGo, Redis, ClamAV, Nginx, Unbound, Docker, and the Ubuntu host packages are now current on their supported stable channels.
The server returned cleanly on the newest installed kernel, all mail services are running, health checks pass, and the outbound queue is empty. Existing SCComp hostname and relay policy customizations were preserved through the supported update process.
We also completed a real round-trip delivery test through an independent verifier. The outbound message was accepted over TLS, the authentication report returned successfully, and SPF, DKIM, and forward-confirmed reverse DNS all passed. Public MX, PTR, DNSSEC, DMARC reporting, MTA-STS, TLS reporting, and certificate policy records were checked as part of the validation.
This work improves security, compatibility, and delivery confidence as the platform moves toward full-scale production.
