Operating System Packages

Dovecot Pro is only supported on Linux, and packages are only created for specific Distributions.

The list of distributions supported for a specific release can be found in the Release Notes for that release.

Supportable Distribution Rules

INFO

Dovecot Pro does not directly support OS distributions. Instead, Dovecot Pro maintains a set of rules that describe when support for a specific OS can be added or dropped.

OS Distribution support additions will be announced in the Release Notes of the version it becomes supported.

OS Distribution support removals will be announced in at least one prior Release Notes before the support is dropped.

• Dovecot Pro will only be supported for distributions that have active support from the OS vendor.
• Dovecot Pro will support the last 2 stable major releases for each supported OS distribution.
• Dovecot Pro packages will be built against the latest OS distribution point release (at the time a version is released). We cannot provide packages built against previous OS releases due to build system limitations.
  • OS Support attaches to a version at the time it is packaged and released. Thus, once released, a Dovecot minor version is frozen when it comes to the OS versions supported on it. Patch Releases will be built using the OS distributions supported for the parent minor release.
  • OS distributions support for a Major or Minor release can be determined by looking at the Release Notes.
• Support for a new OS will only be added in an Dovecot Pro New Generation/Major/Minor Release. OS Support will not be added in patch releases.
  • When support for a new OS distribution is added in a Minor release, a message will be added to the Release Notes indicating that support for the oldest existing supported OS distribution will be dropped in a future release.
• OS distribution support will be frozen once a Dovecot Pro Major Release branch enters Long Term Support (LTS) mode.
