I have configured DKIM:
Dec 27 11:10:03 mailer opendkim[378]: OpenDKIM Filter v2.11.0 starting (args: -x /etc/opendkim.conf)
Dec 27 11:10:10 mailer postfix/postfix-script[551]: warning: symlink leaves directory: /etc/postfix/./makedefs.out
Dec 27 11:10:10 mailer postfix/postfix-script[719]: starting the Postfix mail system
Dec 27 11:10:10 mailer postfix/master[721]: daemon started -- version 3.4.13, configuration /etc/postfix
But the letters are not signed, I connect on port 25, there are no errors, tell me in which configuration file can there be problems? My key is being verified
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: key loaded from /etc/postfix/dkim/mail.private
opendkim-testkey: checking key 'mail._domainkey.domain.com'
opendkim-testkey: key not secure
opendkim-testkey: key OK
Configured exactly as in this guide https://www.linuxbabe.com/mail-server/setting-up-dkim-and-spf
Please tell me which way to look and where I could be wrong with the settings. Thanks in advance to everyone!
