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.
