Is there no way to get SOGo on sme8 anymore ?
Alternatively, & applicable to most add on software, you can install from the developers web site using their tar.gz or zip or whatever file.
It just means you have to do manual configuration & database setup etc.
In many ways it removes being dependent on reliable source of rpms for the add on.
ie you do not necessarily need a contrib rpm package from contribs.org repo etc to install many available add ons, just get them from the web site & follow generic installation instructions.
