Hi, is there a howto for setup new services for 3.1? postgrey can use different backends xmpp seams to need a special server running hhvm firewall (basille seams not to exist on jessie anymore) Mongodb Etc. For real testing all this is needed, but without a defined way what and how to setup it is hard to do so.
For Debian, Postgrey: apt-get install postgrey HHVM: Install HHVm frm its repository and then disable its startscript / systemd unit so that the hhvm service is not starting. xmpp: Have not tested that yet.
In my merge request that added the support for xmpp I linked a snippet containing all commands to set up the required Server: http://git.ispconfig.org/ispconfig/ispconfig3/merge_requests/170
