tSendMail Issue

[Anonymous]

Although it could succeed with the same connection( without any change in setting) sometimes, I get this error every few mins once in talend Cloud data management platform. 

Exception in component tSendMail_2 (J_Sample)
javax.mail.MessagingException: Exception reading response;
nested exception is:

What could be the reason? and how to resolve this?

Hello,

What's your email server? G mail or office 365? Is your network OK with you? We will appreciate it if you could post your tSendMail component setting screenshot here.

Best regards

Hi,

   The job execution engine (in your case, I assume its remote engine) is trying to connect to the SMTP server to trigger the mail. While trying to connect, you are getting the error below.

javax.mail.MessagingException: Exception reading response;
nested exception is:
java.net.SocketException: Connection reset

This could be because there are might be some network or firewall policies which might be stopping the connectivity. Please refer the details in below post. Once you setup proper connectivity between two servers, it should ideally work fine.
