DNS question

I manage the mail server (mail.ourcompany.com) at my company. We provide mail services to a number of clients.

Today CompanyA calls in and reports that CompanyB tried to send them an email, but they never recieved it. According to CompanyB, the mail left there outbox.

The two addresses involved are: bob@companyA.com and john@companyB.com

Our DNS server are authoritive for companyA.com and dns.fakedomain.com are authoritive for companyB.

I "lserver" to dns.fakedomain.com and do a lookup for our mail server: mail.ourdomain.com

The DNS request times out.

But i can ping there DNS server fine...

What is happening? Do they not have an entry on there DNS servers for our domain??

If they dont, what is the process for getting there DNS servers to recognize ours? Is there some kind of prompt-type signal you can send? Or do i have to just physically phone the guys and say: "Hello, please add an entry for our domain..."

Help

NAME
Mail::Verify - Utility to verify an email address SYNOPSIS
use Mail::Verify; DESCRIPTION
"Mail::Verify" provides a function CheckAddress function for verifying email addresses. First the syntax of the email address is checked, then it verifies that there is at least one valid MX server accepting email for the domain. Using Net::DNS and IO::Socket a list of MX records (or, falling back on a hosts A record) are checked to make sure at least one SMTP server is accepting connections. ERRORS
Here are a list of return codes and what they mean: 0 The email address appears to be valid. 1 No email address was supplied. 2 There is a syntaxical error in the email address. 3 There are no DNS entries for the host in question (no MX records or A records). 4 There are no live SMTP servers accepting connections for this email address. EXAMPLES
This example shows obtaining an email address from a form field and verifying it. use CGI qw/:standard/; use Mail::Verify; my $q = new CGI; [...] my $email = $q->param("emailaddr"); my $email_ck = Mail::Verify::CheckAddress( $email ); if( $email_ck ) { print '<h1>Form input error: Invalid email address.</h1>'; } [...] perl v5.8.8 2002-06-09 Mail::Verify(3pm)
