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
