This error was the result of me deleting the fake certificate snake-oil,
which postfix was using by default on sunjammer. I switched to the
*.sugarlabs.org wildcard certificate signed by CAcert.

If we were to use a specific certificate signed by StartSSL, I'm not
sure what the domain clients expect. Maybe whatever is in our MX
records?
