One of our users tried to send mail to the domain education.lu. [...] Exim refuses to talk to those hosts at all with "failure while setting up TLS session". Is this expected behavior in terms of DANE-SMTP? What's postfix doing in this case?

Postfix (2.11.2) seems to be able to talk to education.lu just fine:

Postfix doesn't honor 3.1.3 of the latest DANE-SMTP draft then?

"...SMTP client treatment of TLSA RRs with certificate usages PKIX-TA(0) or PKIX-EE(1) is undefined. SMTP clients should generally treat such TLSA records as unusable."
