I’d like to use Mail-in-a-box for an entire domain (domain.tld) that has mail.domain.tld for the Mail-in-a-box server and then other services, such as the main site are served on server.domain.tld. I used CloudFlare to manage DNS.
I’ve found that I get various errors on the System Status Checks that give me the impression it doesn’t really like this setup.
Are there any instructions that indicate how to set such a scenario up properly?
