Yes, with Phil Pennock doing the test. Example domains that
should fail, but I believe don't with Exim are:

    truman.edu
    techtrack.gov
    mof.gov.tw


http://dnsviz.net/d/_25._tcp.barracuda.truman.edu/dnssec/
http://dnsviz.net/d/_25._tcp.mx1.techtrack.gov/dnssec/
http://dnsviz.net/d/_25._tcp.mail.mof.gov.tw/dnssec/

$ dig +noall +comment -t tlsa _25._tcp.barracuda.truman.edu
