aaPanel_Kern aaP_jasonfomenky Hello, the records of dns domain name resolution are inconsistent with those of the mail server
aaP_marvin26camarillo Your solution works. Set 640 to 644, then restart rspamd to send emails to view the email source code, please replace xxx.com with your domain name. chmod 644 /www/server/dkim/xx.com/default.private systemctl restart rspamd
