The Java Mail service can be configure using a lot of properties, but JMeter allow to set only few of them. It's a list of properties that can be use for config pop3 message store. https://javaee.github.io/javamail/docs/api/com/sun/mail/pop3/package-summary.html My suggestion is add capability for config any properties from list above.
