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.
When ido "host -tmx xyz.com" it gives
2 (SERVEFAIL)

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 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
