Next, sending a SIP dummy request to  the domain www.dnssec-failed.org (www is mandatory) should git this message ( level INFO on master branch)

A more general question:
Would it be possible to generate error codes to the various forward/send/t_relay set of functions so that we know better the type of failure,
like TLS did not validate or DNSsec failed?
