How long is the support life cycle for a specific version/release of MetaDefender Email Gateway Security v5?

OPSWAT provides support on each release of MetaDefender Email Security v4 for 18 months after the publication of the next release of the product (i.e. once a new release is published, you have 18 more months of support on the previous release). However, bug fixes and enhancements are applied only to the next release of a product, not to the current release or historical releases, even when those releases are still under support. In some cases, hot-fixes can be provided for the current release of the product and then incorporated as a regular fix in the next release.

OPSWAT strongly encourages customers to upgrade to the latest release on a regular basis and not to wait until the end of a release supported life-cycle.
