Hi,


I am trying to create zeroshell as a DNS server and do the A/AAAA/MX and Ptr lookup but the documentation doesn't say anything about the configuration also need to define spf check for the sender domain.
Can anyone suggest how to configure the resource records and also configure the SPF records on the Zeroshell.
The mail setup i am using is as below

(Mail Server(wherever.com)------Mail-Gateway-------Outside Server(anywhere.com).
The aim is the let the outside send mails to the inside domain while the DNS(Zeroshell) resolving the domain to the IP address of the gateway which would eventually send mail to the inside Domain. also configure the SPF records on the DNS so that the outside set of IP address should be allowed to mitigate the source address forging.

Please advice ASAP

Regards
