Email Error????

I use a Server 2003 running exchange 2003, we use Sophos PureMessage to scan all emails for virus and spam.

Over the last couple of day a few clients have been trying to send us emails without success, please find below a copy of the NDR they get back

Hi. This is the qmail-send program at

This is a permanent error; I've given up. Sorry it didn't work out.

TLS connect failed; connected to
I'm not going to try again; this message has been in the queue too long.

I know this email is valid cos it receives emails from other clients fine, and a client from Chubb got this back when sending to a valid email address also

I have noticed that the name servers for you domain seem to be configured incorreclty.  Nominet have and listed as your servers.  However, when I do a lookup on your domain has I get and returned.

I would start by sorting my DNS out as this WILL lead to many problems.
