The Proofpoint Security Gateway is the portal which allows you approve and/or block specific senders. These settings do not overwrite the overall security and malware checks conducted by Proofpoint but supplement the mail delivery process.
There are 3 categories of email:
- Threat emails - malware, imposter, credential grabbers, etc. which are always blocked
- Potentially nuisance emails - Spam and bulk emails, which are stored for 30 days but not delivered to your in box (see below)
- Non-threating emails - which are delivered immediately to your in box
To access your quarantine email settings, release messages, etc.:
- Enter https://spamfilter.centre.edu into a web browser.
- This will take you to our single sign on portal. Please enter your credentials and login.
- You will be brought to the following screen where you can manage all settings.

4. Notice the two folders at the top left of the page under the Centre logo
-
- Low Priority mail: Quarantined: The Low Priority folder is where bulk mail (newsletters, business articles) will be listed.
- Spam – Quarantined: The Spam folder is where your junk/spam emails will be.
NOTE: Messages left in these folders will be automatically deleted after 30 days!
