Typo in "encrypted". 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?
