An absolutely noob question I'm sure but I get an email from my web host everyday with a list of a few denied hosts and wondered exactly what this meant. I'm guessing that its a connection refused by the host because of an identification problem but what exactly could cause this issue?
Additionally, I receive the following message and wondered if someone could explain it to me:
reverse mapping - checking getaddrinfo for blah.blah.com [190.xxx.xxx.xx] failed - POSSIBLE BREAK-IN ATTEMPT! : 9 time(s)
