Discard Duplicate Reports
This is a configurable feature that is available in v4.1 and above.
As an admin, you can discard duplicate reports that are imported into the module. This is useful if you are receiving multiple emails regarding the exact same issue repetitively.
On enabling this configurable feature, as soon as the system processes an email for importing, it will check if there is a queued report waiting for moderation with the same IPv4 address. If it detects a duplicate, it will discard the email being processed and just mark it as READ in the inbox to avoid processing it again.
