Anti-Spam Service

The Anti-Spam Service at TWC, provided by Green Radar grMail, is a cloud-based solution that filters incoming email messages based on certain characteristics. If the filter identifies a high probability of spam, a virus, or spoofing, the email is quarantined and not delivered to users.

Users receive a quarantine report email, allowing them to preview and release trusted messages directly. Additionally, the End User Portal Interface (Link: https://grmail.greenradar.com) offers users an alternative interface to manage their quarantined messages, personal allowlist, or blocklist.
