We would like to announce the availability of Kopano Core 8.0.3, a maintenance release that addresses a critical issue. The spooler component of Kopano Core generates malformed message-id headers. This can lead to email being delivered in a spam folder or refused by a spam filter. In some cases it can lead to an email server being (temporarily) blacklisted. More details can be found in ticket KC-224.
All prior releases of Kopano Core are affected by this issue (including 8.1.0 beta 1). If you are running any Kopano Core version we highly recommend you to update to this version. A second beta release for version 8.1.0 will also be released this week, or alternatively you could install one of our nightly builds,where this issue has already been addressed.
Where do I get the packages?
The packages can be found in the repositories, the portal (all require login) and on the download server you can find the nightly builds. The changelog can be found here. If you have any feedback (which is very welcome!) on this release, please use the regular support channels or send an email to feedback[@]kopano.com.
