Hello, 1. I was wondering if and how the following could be achieved - (a). I have one static external IP. (b). I have one internal server install with Zimbra installed (c). I have one internal server install with ispconfig installed (d). I need to forward mail for some subdomains out to zimbra so that zimbra can process it as it wishes using it's default behaviour. 2. Relevant information: (a). I have Email addresses that are in the format of firstname.division.website.com (b). I will need to install websites on each of these subdomains effected to (c). I am effectively trying to take advantage of ISPConfig's DNS capabilities as my domain management company is not that great. 3. Questions: (a). I'm not sure how to achieve this. I understand that the subdomain needs to be added to the DNS - what format should this be typed in? (b). Is it necessary to change anything in zimbra to accomplish this? (c). What records etc need to be created? Thanks and Kind Regards.
