Hi,

I am getting this error.

Sep 11 18:45:47 (none) mail.info postfix/smtp[2326]: 1BE1EF67: to=<
n...@gmail.com>, relay=none, delay=10709, delays=10709/0.3/0.01/0,
dsn=4.4.3, status=deferred (Host or domain name not found. Name service
error for name=gmail.com type=MX: Host

nslookup gmail.com gives me a correct result. By this I am assuming my
/etc/resolv.conf file is correct.
I dont have option to run dig on this system.

I am not seeing any packet going out of system at the time of error. There
suppose to be DNS query packet
going out.. Right ??

And res_search() function in the postfix code is returning error with errno
= 2 which is

#define TRY_AGAIN 2 /* Non-Authoritative Host not found, or SERVERFAIL. */

What might be the problem for res_search to fail ?

I am using postfix version 2.6.4

Regards,
Girish
