Hi Guys It has come to my attention that using server propvided hostnames is not ideal. On SYS control panel, it gives me to option to add a reverse DNS rather than use ns12123.xxx.eu Should I add a reverse for my main DNS ie inspiredsolutionsuk.com. What would I call it? Then, I go into debian, and can I cange everything in the control panel, or should i change files manually, and will this update in ISP control panel? Thanks Lee
The server hostname has to be a subdomain, so something like server.inspiredsolutionsuk.com or server1.inspiredsolutionsuk.com The hostname has to be changed in the files: /etc/hostname /etc/mailname /etc/postfix/main.cf /etc/hosts and afterwards restart the server. Finally you can change it under System > Server services and System > Server config in ISPConfig.
Hi Till Also to add, I needed to put an A record in my dns under the correct domain that the glue records are in, and all is going very well. KRs Lee
can you please tell me, when using a different hostname. does the ip within ispconfig/system/server config/server name/server/ip address/, need to be the same as the A record for the domain used? its just i find when i change that ip all my mail stops working. but then their is one action that i was never doing and thats changing /etc/mailname. thanks
The hostname has to exist as DNS A-Record in dns. The hostname is a subdomain, not the domain itself, so the IP address of the domain does not matter for the hostname, just ensure that you have a valid dns A-Record for the hostnames's subdomain.
so if the server is call server1.domain.tld the hostname is server1 ? so i would change /etc/hostname /etc/mailname /etc/postfix/main.cf /etc/hosts then set hostname in dns record domain.tld. server1. what about within ispconfig? what about the ispconfig server ip ? everytime i change this to one of my failovers the server fails to send mail. maybe because i have missed the last few steps ? cheer man your a legend
