Mail SMTP Server Problem - Joget V-6

Confluence User - 27 Jul, 2021

Hello team, how are you? One of my servers, running Joget 6, started having problems with sending mail. Apparently, the protocol associated with the joget plugin can no longer contact the server. In a recent version of Joget 7 the problem does not appear. Is there any possibility of doing some kind of update? Will the mail have to be migrated to another service? The information in the log:

Caused by: javax.mail.MessagingException: Could not connect to SMTP host: smtp.mail.us-west-2.awsapps.com, port: 465;
  nested exception is:
	javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

According to Google, it could be related to your site SSL certificate or TLS setting. Here are some possible resources to solve your issue:

On another note, the latest OpenJDK disabled the TLS 1 and 1.1 security, see https://aws.amazon.com/blogs/opensource/tls-1-0-1-1-changes-in-openjdk-and-amazon-corretto/ .

Here is a workaround, you can follow the suggestion in https://stackoverflow.com/questions/38205947/sslhandshakeexception-no-appropriate-protocol .

For example: the old setting in /etc/java-11-openjdk/security/java.security is:

jdk.tls.disabledAlgorithms=SSLv3, TLSv1, TLSv1.1, RC4, DES, MD5withRSA, \ DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \ include jdk.disabled.namedCurves

Change it to the following:

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, \ DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL, \ include jdk.disabled.namedCurves

Hi, what version of v6 are you running? I believe this may have been addressed in 6.0.32 according to the changelog.
