Large parts of the german universities now use the DFN MailSupport (= inbound mailrelaying and filtering by DFN). The MX records are in mx.srv.dfn.de, which is not signed (whole dfn.de is not signed). So you can have your own zone DNSSEC enabled, but not the one with the MX. I heard they are working on this. This is also a blocker of our project to have DANE-secured SMTP transport for all bavarian universities. Bernhard
