Question 1

What happens when Proxmox Mail Gateway reaches end of life?

Accepted Answer

When Proxmox Mail Gateway reaches end of life, it stops receiving security patches, bug fixes, and new features. Currently, 4 Proxmox Mail Gateway versions are already EOL. The latest supported version is Proxmox Mail Gateway 9. Running an EOL version exposes your systems to unpatched security vulnerabilities with no official fix available.

Question 2

Is Proxmox Mail Gateway 9 still supported?

Accepted Answer

Yes. Proxmox Mail Gateway 9 is actively supported. It receives security patches and bug fixes. Check the version table above for the full list of supported Proxmox Mail Gateway releases and their exact end-of-life dates.

Question 3

Is it safe to use Proxmox Mail Gateway after end of life?

Accepted Answer

No. Running Proxmox Mail Gateway after EOL is not safe for production systems. Once a version reaches end of life, newly discovered CVEs are published publicly but never patched — leaving your systems permanently exposed. The only safe path is upgrading to an actively supported Proxmox Mail Gateway release.

Question 4

How to upgrade from Proxmox Mail Gateway 7 to Proxmox Mail Gateway 9.x?

Accepted Answer

To upgrade Proxmox Mail Gateway from 7 to 9: (1) review the official migration guide for breaking changes, (2) test your application against the new version in a staging environment, (3) update dependencies that have version constraints, (4) run your full test suite, (5) deploy with a rollback plan. The earlier you start, the more time you have to resolve compatibility issues before EOL.

Question 5

When is the next Proxmox Mail Gateway LTS version?

Accepted Answer

Not all Proxmox Mail Gateway releases have a designated LTS status. Check the version table above — LTS releases are marked with an "LTS" badge. Refer to the official Proxmox Mail Gateway release policy for information on upcoming long-term support versions.
