Hi Team,
I have 4 postfix relay configured with Local DNS cache. I am facing a problem for MX host Look Up for only one particular domain . Whenever I restart named service it works fine for few hours but again the same issue comes back. Please suggest.

Seems to me this is an IPv6 related issue. Check if the problem goes away after you disable IPv6 (search Google for distro-specific ways of doing this).
echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

Hi Ninad, Thanks will test and will let you know the result.

Hi Binad, I verified all the things but was not able to find a single entry which states ipv6 is enabled i checked /etc/sysconfig/network /etc/modprob.conf
I googled to check how to disable as i am using RHEL4AS as my OS it was given to modify few entries in /etc/modprob.conf but i am not able to find any to modify it. The command which you have mentioned is it safe to run as i am working on critical production servers. Please suggest
