How to make TLS logging verbose? (have a TLS problem with evolution)

I have an error that evolution is reporting from the TLS handshaking which is

“Error performing TLS handshake: An unexpected TLS packet was received.”

When I was playing with TLS and mail servers I remember there was a way to get detailed information in the logs about the handshaking process but I can’t find it now. It’s was just a matter of increasing the log level settings somewhere. Does anyone know off hand how to get the logging more verbose for SSL/TLS etc?

For anyone who’s curious it’s a rather strange problem because with two account on the same domain going to the same server setup in evolution (e.g. and one account works fine and the other reports this error. I don’t know whether the problem is on my end, the server end or just some incompatibility however with the detailed logging I am hoping to have enough information to know the answer to that.
