Need Advise on Single Purpose Server Setup

Hi Folks,

actually we’re following the approach of single purpose servers but now I’m struggeling a bit to reduce complexity…

We need a TURN Sever for our BigBlueButton and the docu recomends to let this run on a small vServer. Now the smalest root Server at NetCup comes with 8 GB RAM and 2 cores so I thought it might be a good idea also to move our Mailserver (just the backend, no Kopano or other Groupware) to this machine too.

And suggestions on that or would this be a bad idea?
