Spam and Virus Filtering

Service Description

To reduce the amount of spam being delivered, spam and virus filtering happens at several levels within the email flow at HMC. At the highest level is Cisco IronPort which scans all incoming email sent to your address. Our two email providers, Google Workplace and Microsoft 365, also automatically filter emails. If you use an email application such as Apple’s Mail program or Mozilla Thunderbird, those applications will filter incoming mail as well.

On CIS Managed systems at HMC we utilize Trend Micro Agents. The agent is loaded on all systems controlled by CIS. On Windows and Mac systems, Trend Micro provide threat protection for malware, packer variants, device control, command and control (C&C) traffic, browser exploits, behavior monitoring, web threats, census-based control, and more.


Available to faculty, students, staff, alumni, emeritus, and trustees at HMC.

How to Access the Service

Each morning IronPort sends every user an e-mail with the subject line “Claremont Colleges Spam Digest”. This e-mail will have a summary of all recent quarantined messages. To get a complete list of quarantined messages a user can click on “View all Quarantined Messages” to log into your IronPort Quarantine. This link will change from time to time, so it’s best practice to use the link from your newest digest e-mail. You may also manage your “Safelist” and “Blocklist” when visiting your Quarantine.

Microsoft 365 places quarantined email in a folder called “Junk E-Mail” and Google Mail places it in a folder called “Spam.”

For Trend Micro, you system should already have the Trend Micro Agent installed on your CIS Managed system. If it is not, please contact the CIS Help Desk.

Please contact the CIS Help Desk for additional support with spam and virus filtering.
