Hello,
i try to sent a "hello" email using SMTP Sampler and want to use SSL/TLS on standard port 
465 for this connection.More i want to use TLSv1.2 with the very strong cipher 
"TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384"Currently the handshake fail.
Technially if i change the configuration on my server to also accept TLSv1.1 
and v1.0 then the SSL connection works and the email is sent perfectly.I see in 
the logs that the client (jmeter) and my server aggreed on a cipher comming 
from TLS1.0.Thus in general SSL is working but not with TLSv1.2.
Anyone any idea how i can use SMTP(s) with TLSv1.2 and the above cipher?I tried 
to put this in my jmeter.sh file but seems it does not matter?
JMETER_OPTS="-Dhttps.cipherSuites=TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384"
The smtp sampler has no option to specify the wanted ciphersuites, so the option given above will not be used.
I also installed lates java jdk and i also installed the additional strong 
security pakage and replaced the .jar files in /usr/java/jre.../lib/security
Which jdk did you install exactly?

Have you checked (with openssl or something similar), that your mailserver is capable of TLSv1.2?
