Re: domain level blocking

Blocking domains (or worse, allowing a few domains only) usually ends up breaking things (delivery tests). I can understand a "fully private" server (non routed domain, not connected to the internet) but not really blocking/allowing domains. However, if you want to do something like this, ...
