I would like to keep the existing email server as the primary server to receive all emails.

I want to setup MailIAB as a backup email server in case the Primary is down. I would like to use MailIAB as the primary sending email server. Is there a way to do this to keep all the SPF DKIM DMarc setup properly.

Please provide me with some info, Thanks
