How should I configure email settings using CircleCI docker?

Hello

I am using the Katalon docker image in CircleCI.

I have problems with email settings. I don’t receive email report and I am not able to check emails using javax.mail-1.6.2.

This is the error trying to check email received using javax.mail-1.6.2.

Error when report is tried to be sent:

What could be the problem?
