Hi Folks, One of our production server hardware failures and down, meanwhile i have installed the same COS7 with qmailtoaster to configure the mailbox, it's running fine now with the same ip address.
Once the hardware is replaced, I need to switch on the existing production server to put the same ip and down the standby server. My question is, do i need to change any configuration for the letsencrypt and dkim for the existing server, because i have installed again letsencrypt ssl and dkim config in dns server for standby server. Appreciate anyone advise and help. -- *Regards,Manikandan.C*
