Thanks Skalli,
After applying the config change and adding
[email]
sslVersions = *,-ssl2
cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH
Got rid of that error now getting
command="sendemail", [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:741)
Running the below command returns the following
sudo ./splunk/bin/splunk cmd openssl s_client -connect smtp-relay.gmail.com:587 | awk '/Protocol/ || /Cipher/ || /Verify/'
140005157344960:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:s23_clnt.c:827:
New, (NONE), Cipher is (NONE)
Protocol : TLSv1.2
Cipher : 0000
Verify return code: 0 (ok)
The server has other applications successfully sending emails via the above mail server so I am missing something in the config.
