If you need a DNSSEC-enabled destination to test your DANE setup, send a
message to sink at It will accept your message and discard it.

Check your log for a line "to". If it reads "Verified TLS
connection" (Postfix) your DANE setup works properly.

Here's a log example:

Apr  8 19:52:31 mail postfix/smtp[28741]: Verified TLS connection established to[2001:1578:400:111::3:1]:25: TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
