I believe we have a miscommunication, that’s alright let me clarify.

Simplified Privacy is technical support.  We don’t run the VPS.
We setup for you/customers services you like on a third party VPS that you pick, with your domain choice.

So we aren’t hosting the email, we’re providing the software and technical support.
The challenge is getting 3 services, with different web panels, to all work without issue.
So once we set it up, you lock US, meaning Simplified Privacy out. 

 admittedly I didn't know that, but it just changes the name of the entity that has full access to ones system. you should offer support to run this stack on a fully encrypted root server. 

 We do offer it on a root w/ encryption.  But as you just said, they can still snapshot memory as ALL email has this issue.
But there is still privacy above what proton has, and you get other services such as XMPP and Cryptpad with it, so its good for small businesses that need email to function 

 I meant root server as in contrary to vps. of you have exclusive hardware, you have a shot at real privacy. 

 Oh.  That'd be hella expensive for just email only.  But if you have a bunch of other stuff running too, then yeah
