We are seeing a lot of exceptions being thrown in production about our email listeners and none of them have any impact. Some of them are showing "unknown user name or bad password" even though it is still valid.

We run PRPC 7.1.7 and use POP3 with SSL for receiving messages.

We are not sure if it's because of Exchange or it's due to the Listeners themselves.

Did anyone else experience something similar?

Is there a way to fix this?

Examples:

services.email.EmailListener) ERROR EMAIL.AppProcessingCase.Listener XXXXXX - Caught exception while connecting to email server(s)

javax.mail.MessagingException: Could not connect to SMTP host: XXXXXX, port: 25;

  nested exception is:

  java.net.ConnectException: Connection refused

services.email.EmailListener) ERROR EMAIL.AppProcessingCase.Listener XXXXXX - Caught exception while connecting to email server(s)

javax.mail.MessagingException: Exception reading response;

  nested exception is:

  java.net.SocketException: Connection reset

services.email.EmailListener) ERROR EMAIL.BPEmailListener.Listener EmailListenerOperator - Caught exception while connecting to email server(s)

javax.mail.AuthenticationFailedException: Logon failure: unknown user name or bad password.
