Hi
My configuration is working fine, and both outgoing and incoming emails are working correctly. However, when I check the mail-tester, it shows that DKIM is missing. Could you please advise on how to fix this issue?
My config

Please screenshot the executed command tail -n 100 /opt/BillionMail/logs/rspamd/rspamd.log after you send any email.
Same issue for me :
Containers are started with "billionmail_"
billionmail_webmail-billionmail_1
billionmail_dovecot-billionmail_1
billionmail_core-billionmail_1
billionmail_postfix-billionmail_1
billionmail_rspamd-billionmail_1
billionmail_redis-billionmail_1
but in the code we only see things like "billionmail-"
Please screenshot the executed command tail -n 100 /opt/BillionMail/logs/rspamd/rspamd.log after you send any email.
