The problem is that the fix introduced with CAMEL-8163 makes matters worse. The SSLSocketConnectionFactory is used for the connection to the SMTP server, not for the socket upgrade to TLS.
The fix would be to set the properties mail.[protocol].ssl.socketFactory instead of mail.[protocol].socketFactory.
