I am trying to read from an email. For this, I have used mail reader sampler and added javax.mail.jar file to lib folder. But when I run my test, I am always getting 500 error with this error:

Response message:com.sun.mail.util.MailConnectException: Couldn't connect to host, port: imap.gmail.com, 993; timeout -1;
nested exception is:
java.net.ConnectException: Connection timed out: connect

Can you help?
