Hello all!
I am wanting to monitor whether my mail server is successfully using DANE.
At first I was confused, as `smtp_tls_loglevel = 1` only showed TLS
being verified. E.g.:
postfix/smtp[930739]: Verified TLS connection established to
mail.sys4.de[2001:1578:400:111::7]:25: TLSv1.2 with cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
However, with `smtp_tls_loglevel = 2` I see:
postfix/smtp[931046]: mail.sys4.de[194.126.158.132]:25: Matched DANE
EE certificate at depth 0: 3 1 1
236831AEEAB41E7BD10DC14320600B245C791B338121383D5A2916F7EF97B49B
...
postfix/smtp[931046]: Verified TLS connection established to
mail.sys4.de[194.126.158.132]:25: TLSv1.2 with cipher
ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)
Is there another way to monitor whether DANE is functioning other than
log level 2, which is really rather verbose and making logs hard to read?
Thank you in advance!
