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 hub1.digitalwigwam.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
TLS connect failed; connected to 18.104.22.168.
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
