TLS Certificate problem?
Posted on 2011-10-21
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
