+If your server does not support this, you may have to specify --sslproto

 Quickstart
 ----------
 
+Use an up-to-date release of OpenSSL 1.0.1 or newer, so as to get
+TLSv1.2 support.
+
 For use of SSL or TLS with in-band negotiation on the regular service's port, 
 i. e. with STLS or STARTTLS, use these command line options
 
-    --sslproto tls1 --sslcertck
+    --sslproto auto --sslcertck
 
 or these options in the rcfile (after the respective "user"... options)
 
-      sslproto tls1   sslcertck
+      sslproto auto   sslcertck
 
 
 For use of SSL or TLS on a separate port, if the whole TCP connection is 
-SSL-encrypted from the very beginning, use these command line options (in the 
-rcfile, omit all leading "--"):
