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.
18.104.22.168: address not listed for hostname h1870666.stratoserver.net
My primary IP for this server is: 22.214.171.124
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:
126.96.36.199 h1870666.stratoserver.net h1870666
188.8.131.52 h1870666.stratoserver.net h1870666
