ISPConfig 3.1.15 Released

What’s new in ISPConfig 3.1.15

This ISPConfig version provides support for the Rspamd email spam filter, which replaces amavis as the default spam filter in ISPConfig. Amavis has become less effective in recent years, so we looked for an alternative and found that Rspamd is really effective and a good Amavis replacement. Amavis is still fully supported so that existing installations are not affected and newly installed systems can also use amavis if you want to keep amavis. In the next few days we will publish a tutorial that shows how to convert an amavis-based system to Rspamd. This version also contains some bugfixes. For details, please see the changelog.
