Hi, If I am hosting multiple domains in Mailcow; 1. How do I ensure rDNS resolves to different domain names? 2. If I setup firewall to be 1:1 for external to internal (virtual IPs) for each domain, how do I ensure each domain will bind to virtual IP to go out the correct public IP address? Any assistance would be very much appreciated. Cheers

Bind Domain Name to IP Address

Hi,
If I am hosting multiple domains in Mailcow;

How do I ensure rDNS resolves to different domain names?
If I setup firewall to be 1:1 for external to internal (virtual IPs) for each domain, how do I ensure each domain will bind to virtual IP to go out the correct public IP address?

rDNS needs to match your mailcow hostname, not all maildomains.

Many thanks for your kind response.

So all maildomains within Mailcow host will use the same DNS entries as Mailcow host domain except if I want dkim key different for each maildomain?
