Service permissions are set wrong.

You have explicitly changed the login process user above.

This group isn't right.. The default is taken from user's default group,
so just don't set it.

Here you're using default_login_user, which most likely isn't the same
as what the login processes are using ("dovecot").

So your solution is to remove the explicit user=dovecot from login
services and then possibly set default_login_user=dovecot if you really
want that (dovenull user is the default and preferred one).
