Sendmail not working anymore after resolv.conf change

Hi there,
I am having a small issue with the mail function on our controllers. Recently we set up all the boxes as NFS slave servers and mail sending was not affected. We then had to change the servers addresses in resolv.conf and now email is being queued and not being sent.

I have restarted the sendmail on the machines and the issue still is there. What could be the issue? We have other controllers with the resolv.conf and the mail function does not seemed to be affected - the only difference is that they are clients not slaves.

I have changed back to the old ip addresses in the resolv.conf and mail sends fine but these will be going offline very soon..I know this give me a clue that it is these addreses that are causing the conflict.

I have also compared the mailsevrs files and they are also matched.
What else could I check? I have looked at the fstab comparing them with other controllers and they are matched.

NAME
innmail - Simple mail-sending program SYNOPSIS
innmail [-h] [-s subject] address [address ...] DESCRIPTION
innmail is a Perl script intended to provide the non-interactive mail-sending functionality of mail(1) while avoiding nasty security problems. It takes the body of a mail message on standard input and sends it to the specified addresses by invoking the value of mta in inn.conf. At least one address (formatted for the MTA specified in inn.conf, if it matters) is required. innmail will sanitize the addresses so that they contain only alphanumerics and the symbols "@", ".", "-", "+", "_", and "%". innmail was written to be suitable for the mailcmd setting in inn.conf. OPTIONS
-h Gives usage information. -s subject Sets the Subject: header of the message. A warning is issued if this option is omitted. EXAMPLES
This sends a one-line message to the local user "joe": echo "A one-line message." | innmail -s "Simple message" joe innmail by default is used by INN for sending nightly reports and control message reports. BUGS
innmail fails on addresses that begin with "-", although one might hope that the news server will not need to contact any such addresses. There are many "correct" addresses that will be silently modified by the sanitization process. A news administrator should be careful to use particularly sane addresses if they may be passed to innmail. HISTORY
innmail was written by James Brister <brister@vix.com> for InterNetNews. This manual page was originally written by Jeffrey M. Vinocur. $Id: innmail.pod 7851 2008-05-26 19:33:08Z iulius $ SEE ALSO
