New Service from IMSS: Mail Protection Gateway

05/04/2017
Dear Faculty, Staff and Students,  

IMSS is implementing an email security service called the Mail Protection Gateway (MPG), provided by Cisco Email Security. With its increased accuracy, this service helps protect against advanced email threats and reduce unsolicited email (spam). The MPG will be an additional tool to help fight against spammers and hackers.      

What you need to know  

Schedule: Effective May 23rd at 5:30 PM, all @caltech.edu email addresses will begin using this service.    

MPG Quarantine Overview  

  • Receive a weekly summary on Monday mornings with information about new items in your quarantine  

  • Suspected spam is quarantined for up to 45 days   

  • Direct access to view your quarantined items at any time at https://quarantine.caltech.edu (bookmark for easy reference)  

Please keep in mind that the MPG Quarantine is not the same as the spam folder in your email application. Your email application (Outlook, Thunderbird, Mac Mail, etc.) may classify email as spam independently of this service, therefore you should continue to check your local spam folder.     

Also note that messages containing .zip attachments will no longer be restricted unless malicious content is detected.    

If you have questions or require assistance, please contact the Help Desk at x3500, help@caltech.edu, or at https://help.caltech.edu (request type IMSS > Email & Calendar > Mail Protection Gateway).   

Thank you,     

IMSS MPG Project Team
