Description

Those processors have 'Delete Messages' property but even if user configured it to 'true' messages are not deleted from mail server.

AbstractEmailProcessor which is a superclass for both processors, has been using:

emailMessage.setFlag(Flags.Flag.DELETED, this.shouldSetDeleteFlag);

However, since we are using Spring mail, the underlying receiver does not close the inbox connection so messages are not deleted.

Instead, we should use:

receiver.setShouldDeleteMessages(boolean)

To specify whether it should delete fetched messages or not.
