Hello, I'm rather new to administering a Mail server, I'm running Exim 3.35 and qpopper v4.04 on Debian Woody 2.4.20 My question is in my syslog, I keep getting this canonical error when anyone on my 13 subnets checks thier email with outlook or outlook express. Is there a way I can turn off the canonical lookup for something like 192.168.0/24.0/24? Is this even a problem other than filling up the syslog? Am I even thinking in the right direction?
