tSendMail : Unsupported or unrecognized SSL message

castiellll — Thu, 17 Dec 2020 11:39:41 GMT

Hello,

I am trying to use a tSendMail but I am getting the following error :

Exception in component tSendMail_1 (general_test)

javax.mail.MessagingException: Exception reading response;

nested exception is:

javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

at com.sun.mail.smtp.SMTPTransport.readServerResponse(SMTPTransport.java:1462)

at com.sun.mail.smtp.SMTPTransport.openServer(SMTPTransport.java:1260)

at com.sun.mail.smtp.SMTPTransport.protocolConnect(SMTPTransport.java:370)

......

Here is my component :

Does anyone know a way to fix it ?

Thank you

I am not sure if this job is on-premise or on cloud. I have enforced SSL in couple of my on-premise jobs successfully and this is what I did.

If you want SSL to be enforced, you may have to include a tSetKeyStore component and give the path where your cert/jks is placed. tSetKeyStore should be before tSendMail_1.

I think the problem comes from TLS1.2.

How can I force tSendMail to use TLS1.2 ?
