Manage Suspicious Email Using Mimecast
Mimecast Email Security provides a suite of detection and prevention tools that enable automated blocking of malicious email, and a way to manage spam. It provides a function that holds spam until the recipient chooses to release, permit, or block the message from being delivered to their inbox.
Twice a day, you’ll receive an email from no-reply@georgetown.edu letting you know of any held spam messages you’ve received and you can choose to take action.
Managing Emails Identified as Spam
In every digest notification, you can take the following actions for each of the emails listed:
- Release/Release All – Delivers this email or all messages, but future messages from this sender may still be blocked.
- Permit/Permit All – Allows this email or all future messages from this trusted sender to be delivered.
- Block/Block All – Blocks this email or all future messages from this sender.
*Please note that these messages will expire and be unrecoverable after 30 days.

Manage Emails in MySPAM Portal
You can also manage held emails by logging in to the held email location (i.e., the MySPAMPortal) using your NetID@georgetown.edu email address and NetID password, and selecting the portal location.
