Hello
I have a postfix/dovecot/roundcube server working.
I have configure DKIM in the server and in my DNS zone.
When I send a test email to Gmail account and on the right side of an opened email message in Gmail, if I click the show original button from the drop-down menu, I can see the authentication results. => Which is
DKIM : 'PASS' with domaine mydomain.net
But when I try
https://www.mail-tester.com I get only 9/10 because it says message not sign with DKIM
Is there many level of DKIM ?
How can I double chek if Google ou mail-tester.com is wrong?
PS : when I test on the server It seem's Ok
sudo opendkim-testkey -d mydomain.net -s default -vvv
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: checking key 'default._domainkey.mydomain.net'
opendkim-testkey: key not secure
opendkim-testkey: key OK
