how to fix: address not listed for hostname?
Debian perfect server installation with ISPCFG3 and 2 IPs.
I added the second IP to my server as advised by Falko in another thread, then I started getting these warnings in my mail logs. To fix them, I added a reverse DNS entry for the second IP and thought I got rid of them but every now and then, these warnings still appear in my logs.
184.108.40.206: address not listed for hostname h1870666.stratoserver.net
My primary IP for this server is: 220.127.116.11
Anything I forgot besides the reverse DNS?
I also added the second IP to /etc/hosts like this but I am unsure if this is right:
18.104.22.168 h1870666.stratoserver.net h1870666
22.214.171.124 h1870666.stratoserver.net h1870666
