Hello,
I enabled postscreen, looks very good but on the /var/log/mail.log I noted two warning messages:
warning: getpeername: Transport endpoint is not connected -- dropping this connection
and
postfix/dnsblog[1870]: warning: dnsblog_query: lookup error for DNS query 180.212.85.209.list.dnswl.org: Host or domain name not found. Name service error for name=180.212.85.209.list.dnswl.org type=A: Host not found, try again
What does they means and how can I fix?
Thank you.
