Re: DNS/Minires problems w/ Exim-4.20 on Cygwin


Hi,

Thanks for the detailed report. I just came back from vacation,
hence the delay. Here are a few comments:

>Minires: Windows domain name "tais.adroot.toshiba.com"
>Minires: server "207.46.138.11"
>Minires: server "207.46.138.21"
>Minires: server "159.119.100.48"

The following two lines indicate that you have a resolv.conf
file that duplicates the info provided by Windows, but without
159.119.100.48. That's OK, but unnecessary.
>Minires: resolv.conf nameserver 207.46.138.11
>Minires: resolv.conf nameserver 207.46.138.21

>Minires: search yahoo.com type 15
>Minires: query yahoo.com type 15
>Minires: Answer from 158a2ecf to query to 158a2ecf. Error 2. Count 0.
>DNS lookup of yahoo.com (MX) gave TRY_AGAIN
>yahoo.com in dns_again_means_nonexist? no (option unset)
>returning DNS_AGAIN

It looks like 207.46.138.21 received the query correctly and replied
with the error code DNS_AGAIN, which is supposed to mean
#define TRY_AGAIN       2 /* Non-Authoritive Host not found, or SERVERFAIL */

When I try the same command here I get

**************
dnslookup router called for rub1k@yahoo.com
  domain = yahoo.com
Minires: Windows domain name ""
Minires: server "151.203.0.85"
Minires: server "151.203.0.84"
Minires: search yahoo.com type 15
Minires: query yahoo.com type 15
Minires: Answer from 5400cb97 to query to 5400cb97. Error 0. Count 3.
DNS lookup of yahoo.com (MX) succeeded

***************
Next I created an /etc/resolv.conf file with 207.46.138.11 (one of
your servers) and it worked too:

Minires: Windows domain name ""
Minires: server "151.203.0.85"
Minires: server "151.203.0.84"
Minires: resolv.conf nameserver 207.46.138.11
Minires: resolv.conf 
Minires: search yahoo.com type 15
Minires: query yahoo.com type 15
Minires: Answer from b8a2ecf to query to b8a2ecf. Error 0. Count 3.
 
However when I try 207.46.138.21, I get the same error as you do.
So it must be a problem with that server. Try removing it from your 
resolv.conf, but add 159.119.100.48

Also what happens when you dig @207.46.138.21 ?
