If I can not contact them by EMail I have to do an expensiv long distance call.
The actual text of the error message comes from OpenSSL, and it is very misleading. Ignore the "sslv3" part of it. OpenSSL uses internal routines named "sslv3" that will autonegotiate the protocol level with the peer.
As I recall, you are using a relative older version of Courier. Since then, the OpenSSL API have been updated, and the default settings in the current version of Courier's configuration files will be sufficient to negotiate any protocol that's common to both the client and the server.
Also, the current version of Courier should handle TLS negotiation failures automatically. The unsent message will not initially bounce, and the next connection attempt will not attempt to negotiate TLS with the remote server.
