Set mail crypt private password with OAUTH?

In fact now that I looked through your configs one more, this is already what you are doing, except you are exporting the private key password in three different places.

So basically, if you do `doveadm user foobar` it should already give you a correct key.

You can see if the key is correct with `doveadm mailbox cryptokey export -u user -U`
