DNS config preventing mail delivery

Hi

Please can you help on this: the Net Admins decided to use DNS to resolve names, so this is preventing mail being delivered when using commands like
Code:
date | mailx -s "test" abc.xyz@asdf.xx.yy

.
What we were asked was to edit
Code:
/etc/resolv.conf

and add 3 entries, in all servers

Net::DNS::RR::AAAA - DNS AAAA resource record SYNOPSIS
use Net::DNS; $rr = new Net::DNS::RR('name IN AAAA address'); $rr = new Net::DNS::RR( name => 'example.com', type => 'AAAA', address => '2001:DB8::8:800:200C:417A' ); DESCRIPTION
