Hello, I tried to set skip-name-resolve and everything was crewed up. Mail server stopped working. I got the Database connection error from mail log. IS there anyway to avoid this issue?
The services like postfix etc. connect to MySQL on localhost and when you disable name resolving, then connects to localhost must fail. The only way to avoid that is to search in all files for localhost MySQL connections and change them to IP address 127.0.0.1.
