Over the next few weeks, we will be moving to the new PKI backend here, which means there will be new SSL/TLS certificates on everything from the websites to smtp, imap, etc.
To make sure you are prepared, please visit our new Certs site here and download the SOSDG Root CA Level 0 certificate and import it into your keychain/certificate store. Old certificates and the original Root CA will continue to be valid until at least Jan 1st, 2011.
