🍂🐄 Mootember Update 2025 | MTA-STS Support, SOGo 5.12.3, Rspamd 3.12.1, and More

Caution

mailcow now requires jq to be installed on the host system in order to operate with the redesigned IPv6 controller.
If it's missing, please install it before running the update, this tool is mandatory and will not be removed in a future release.

Caution

This update introduces a brand-new container: postfix-tlspol-mailcow, which adds outbound MTA-STS support to Postfix.
After updating, verify that the new container is running correctly by reviewing the logs:

docker compose logs -f --tail 200 postfix-tlspol-mailcow

If you encounter CPU Problems or continuous restarts, rebuild the image manually:

docker build -t ghcr.io/mailcow/postfix-tlspol:1.0 data/Dockerfiles/postfix-tlspol
docker compose up -d
