There have to be special contracts and much more to sign for company's and server admins then to have email secure and private. ( if such options are easy possible)
With so easy to read this is totally not done in most Country's.
Therefore if such option is there yes or no switchable.
Then there is by LAW (
https://en.wikipedia.org/wiki/General_Data_Protection_Regulation) a kind of rule.
For contracts and having heavy auditing on this, also you have to have the audit data save to be unchangeble and so stored and very very safe for many years.
So total b.ll sh.t to peeping / spying options as this should be not possible at all.
If using other tools for that, it is your thing , you're hacking then users private data so not allowed also!
If you don't like such LAWS , you like everybody out of this forum can have a look at all your own private data then?
You better take a look at the present ways, and better teach your custommers so you don't need this at all
You those wo want this, don't forget you are also reading then personal private mails not only from users on the DA server
but from also random private persons! those wo did send mail to mailboxes on the DA server!
they didn't give a permission to you all to read their mails!
A admin should by default not have email / file read rights.
If taken / change only with permission and full audit and some signed text in contract.
You can ask some in Germany Datenschutz and so on.
I am no law person but that is so obvious.
2005 a admin was fired for such in German:

So don;t make it easy todo, it should even be better protected and in log files staying vissible if one does!
If needed for Customers with their written permision and it is time consuming send a nice BILL then you can all earn some more extra money put this in the terms and yes ..
I burned my hands myself almost in the past, someone asking to place backup mails from a left / ex CEO back after he did deleted ( he said private mails only)
