Can emails be incorrectly evaluated and blocked even though they are not spam?

This is theoretically possible, but it is extremely unlikely. This is then a so-called "false positive". Our technical department has determined the threshold values for spam detection in extensive and complex tests, so that our false positive rate is below 0.0004%. The threshold values are adjusted hourly to the requirements.

Should you ever want to report a false positive, you can send it to our reporting address at any time:

Report as forward (False Negative and False Positive)

• False Negative -> false-negative@hornetsecurity.com
• False Positive -> false-positive@hornetsecurity.com

Send the relevant email to one of our reporting addresses. Use the False Negative address for unwanted emails. For falsely intercepted emails use the False Positive address.

The FPs/FNs examples in the attachment must be sent as ".eml" format to the above addresses.

Please note that you will not receive an individual reply, as the corresponding process is automated. However, we will make sure that the rules are adapted and that this email is correctly categorized in the future.
