Anti-Spam Service User Guide

HKMU Anti-Spam Service User Guide

Anti-Spam service (Green Radar grMail) is a cloud-based mail-filtering solution. In HKMU, incoming email messages pass through Green Radar. The filter looks for certain message characteristics and performs actions on the message when these characteristics are found. If spam probability, virus or spoofing is found, the incoming email message is quarantined and does not deliver to users.

Users will receive quarantine report email notifying you a summary of quarantined messages. You can preview the message to check the quarantine reason and email content, release the message directly from the quarantine report email if you confirmed the quarantined email is trusted.

Alternatively, the End User Web Interface (Link: https://grmail.greenradar.com ) provides users with an additional interface to manage their quarantined messages, and personal allowlist or blocklist.
