TLS Certificate problem?

One of my customers has had an SBS 2003 server running for a few years with no real problems, in the UK recently BT (their broadband provider and domain host) had a major outage (i think due to spamming) since then the emails from major customers (centrica, John Lewis etc) have not been getting through, the bounce back with the error TLS connect failed; connected to 81.143.xxx.xxx (the customers server IP address). Smaller companies emails still get through. BT say that changes made to their system will mean that my customers server now need to use a certificate. What is the best proceedure for this? do we need a certificate generated by a Certificate provider or can we generate one ourselves? What is the correct procceedure for installing the certificate on a Windows SBS 2003 Server? Thanks

You will need to run the Configure Email and Internet Connection Wizard from Server Management > Internet and Email > Connect to the Internet.

During the wizard process it will allow you to make and install a self-signed certificate that will do the job.

Run email test at http://www.checktls.com to see if TLS is working and if you have the cert installed correctly.

If so, post the complete bounce message that a customer receives and maybe we can see something.

Thanks for your help but I found out that I needed to remove the old certificate and then create a new on, all working correctly now
