Hi Eric, I have done the above steps earlier in my production server, after downtime I did not do anything. When I run the command cat /var/qmail/control/dkim/public.txt dkim record is displayed and I have copied and put it into our dns server. i have put the standby server text into dns record during production server down. I have removed that and re-configure in dns server after up the production server, but not working.
Can I do again the same above steps to re-generate the key on the production server.
