The Cyrus team is proud to announce the immediate availability of a new version of Cyrus IMAP: 3.0.11

I'm trialling hosting the release files using Github's releases feature.  Please use the Github download links if possible, and advise if you have any problems!  (It may even download faster due to Github's content delivery network.)

This release contains a fix for a potential data loss issue when upgrading mail servers containing messages that existed prior to Cyrus 2.3.  For details, please see the release notes.  If upgrading a service that has been around a long time, consider upgrading to 3.0.11 rather than one of the earlier 3.0 releases.

Please consult the release notes and upgrade documentation before upgrading to 3.0.11:

And join us on Github at to report issues, join in the deliberations of new features for the next Cyrus IMAP release, and to contribute to the documentation.

On behalf of the Cyrus team,

Kind regards,

ellie timoney
