Error:

The below error occurs when we ty to send an email:

Caused by: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

How to Reproduce:
  1. Edit the file $JAVA_HOME/conf/security/java.security in a text editor. 
  2. Add the entries TLSv1, and TLSv1.1, from the following line of that file:
    jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES,

Resolution:

Method A
Modifying the file java.security inside the JDK install directory:
  1. Edit the file $JAVA_HOME/conf/security/java.security in a text editor. 
  2. Remove the entries TLSv1, and TLSv1.1, from the following line of that file:
    jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES,
  3. Restart the application

Method B
Passing a custom java.security file as java command line flag:

  1. Copy the file $JAVA_HOME/conf/security/java.security to a different location, for example /home/ojdk/oldTLS.security
  2. Remove the entries TLSv1, and TLSv1.1, from the following line of the file oldTLS.security:
    jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES,
  3. Add -Djava.security.properties=/home/ojdk/oldTLS.security to the java command line in the application start script.
  4. Start the application

On Java 8, the java.security file is located in the following directory: 

$JAVA_HOME/jre/lib/security
