Also the description should include any instructions/guidance on how to configure NiFi and/or the processor in order to use IMAPS, especially since the default value is true. When I tested this, I got the following error: Failed to receive messages from Email server: [javax.mail.MessagingException - sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target I assume I'm missing something like a truststore but not sure where to set that up. Is it possible instead of a "Use SSL" property to use an SSLContext Controller Service?
