mod_component: Require 'from' attribute on stanzas by default The old behaviour of falling back to the component domain when it is missing has been merged into the logic for the existing "validate_from_addresses" option (which is strict by default). ejabberd already rejects component stanzas with no 'from' (as the XEP requires), and this has led to compatibility issues for components that were seemingly working fine with Prosody.
