Hi all, My maillog is full of lines like the following
Sep 2 10:22:56 myhost /usr/local/sbin/popper[8503]: (v4.0.3) Unable to get canonical name of client xx.xx.xx.xx: Unknown host (1) These occur about 3 times a minute. They are making it difficult to see genuine entries in the maillog. Is there any way of filtering them? I would like to leave reverse DNS lookups on, but I would like to do one of the following (in order of preference): a) turn off reverse for this host b) log the messages elsewhere c) stop logging errors for failed reverse lookups d) attack with an axe the isp resonsible for providing reverse DNS for the IP range in question Could anybody please help? Cheers Rich
