Let's say I have a computer A which is running postfix, computer B is running tinydns. On domain project.domain.com I'm running httpd server and other server with DNS (tinydns) have entries like =project.domain.com:1.2.3.4:86400 and +project.domain.com:1.2.3.4:86400 where 1.2.3.4 is correct addres for server which runs httpd server. I also have a postfix mail server on 1.2.3.5 which I'd like to work with this domain (project.domain.com). I'm afraid that if I add another alias like +project.domain.com:1.2.3.5:86400 to tinydns configuration - it could break. How that entry should look like? Thank you for any hints.
