If it's not on the datasheet, it's not been tested or is supported.
Typically, we will support (i.e. test) the versions that are available to us at the time we code freeze. We also tend to support the latest "free" version and the corresponding Enterprise versions of both RedHat and SUSE. We don't provide support for the paid-for consumer versions of SUSE.
That said, other users have persuaded Scalix to install on some of the "free" enterprise versions from CentOS and also SUSE 10.0 ( not OSS ) so you need to search through the forums to find out how that was done.
If that doesn't help, take a look at Scalix CE Raw which is, basically, an unpackaged version of Community Edition but there are manual installation instructions at our
CE Raw site.
