We have a use case where we’d like certain domains to not auto-complete based on the other users in that domain. Ideally you’d just put it in _any_ valid email and Sogo will accept it. Right now Sogo, for ex., in the calendar share does not allow this. It must be an auto-completed user. Ideally we’d just disable autocomplete everywhere and rely on this behaviour, but there is no option for that either.
