tSendMail - javax.net.ssl.SSLHandshakeException: No appropriate protocol

[ETL666]

Hello everyone !

I have some trouble with the tSendMail ! I use microsoft office server so it's TLS protocol.

But i get this error message :

Exception in component tSendMail_1

javax.mail.MessagingException: Can't send command to SMTP host;

 nested exception is:

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

It seems it's because of TLS version because Outlook don't use

TLS 1.0

anymore

So i have checked for some solution and I found that I have to upgrade tSendMail : https://community.talend.com/s/article/Issue-with-tSendMail-and-TLS-version-ElVmA

But I can't do it

Also, there is something strange thing because tSendMail works only with java jdk 15.0.1 only this version in my side (JRE 1.8)

Does someone have any solution ?

Thanks in advance !

Hi

As explained in this page, the TLS 1.0 and TLS 1.1 has been disabled in JDK 8 or 11, try the solutions and let me know if it works.
