Hello, we have a message to *@transfennica.com. Postfix lookup the MX ( mail.spliethoff.nl) and try to validate vi DANE. That fail: Jun 9 11:55:00 mail postfix/smtp[12345]: warning: TLS policy lookup for transfennica.com/mail.spliethoff.nl: TLSA lookup error for mail.spliethoff.nl:25 Jun 9 11:55:00 mail postfix/smtp[12345]: warning: TLS policy lookup for transfennica.com/smtp.spliethoff.nl: TLSA lookup error for smtp.spliethoff.nl:25 Jun 9 11:55:00 mail postfix/smtp[12345]: QUEUEID: to=, relay=none, delay=0.75, delays=0.13/0/0.62/0, dsn=4.7.5, status=deferred (TLSA lookup error for smtp.spliethoff.nl:25) OK, I went to dane.sys4.de, (thanks for the service) but simply got "transfennica.com don't use DNSSEC" It would be helpful the validator would do the MX lookup and check the MX hosts like postfix does. Thanks, Andreas -- A. Schulze DATEV eG
