How does email filtering work?

All incoming and outgoing email is filtered by the Proofpoint Protection Server. Messages that contain a virus, or spam, or inappropriate content are “scored.” If the messages score high enough, the messages are sent to the Quarantine, where users can “take a look” at them. Only Clemson users that are the recipients of the email are notified of the quarantine...senders are not notified. 

What is the Quarantine?

The Quarantine is a location on a server where email messages are stored temporarily because they might contain spam, a virus, or inappropriate content. If the message is infected with a virus, the virus is removed. You can release your messages from the Quarantine if you determine that they are not spam. Messages that are not released from the Quarantine are automatically deleted after a designated period of time. 

What is an End User Digest?

If email messages addressed to you were sent to the Quarantine, you will receive an email notification, called an End User Digest (or Digest), in your mail box. The Digest provides you with a list of the messages addressed to you that are stored in the Quarantine. You can look at the message subject headers to determine their content and as a result what actions you want to apply to the messages.

You may also elect to receive an empty Digest, which is simply an email message indicating that you have no messages in the Quarantine. You may want to receive a Digest even if it doesn't contain any messages, so you can continue to manage certain aspects of your email. In order to receive the empty digest, you must click on "Manage My Account" within a digest which will take you to your account settings on the ProofPoint server.

How do I view my digest?

You can log in with your Clemson user name and password here.

What do the options in the Digest mean?


There are various options within a digest. Here is a brief explanation for each:

  • Request New End User Digest
    • This will send a new summary digest showing all current messages in the quarantine.
  • Request Safe/Blocked Senders List
    • This will send an email summary of your current safe/blocked list
  • Manage My Account
    • This will take you to the account management interface on the ProofPoint server. Here you can modify your safe/blocked lists and change some settings under your profile like opt to receive empty digests and change your default language.
  • Help
    • Takes you to the help page on the Proofpoint server.
  • Release
    • Releases the message from quarantine and delivers to you via email. Note, that this only affects the current message and has no affect on future messages for this sender.
  • Safelist
    • Adds this sender (or the sender's domain) to your safelist. Future messages from this sender will not be quarantined.
  • Not Spam
    • This reports to the system administrators that the message was not spam. Proofpoint will update its scanning engine about the message characteristics and it will not be quarantined in the future.
  • Score
    • This represents the score for that individual message. Higher scores represent a higher likelihood of the message being spam. A spam score of 100 is automatically discarded and not delivered to quarantine

Why haven't I received a digest?

You will only receive a digest if there are messages in your quarantine. Some messages that are known to be spam with a score of 100 or automatically discarded. Only messages that are scored within a certain range will go into the quarantine. That range can be adjusted as needed to better meet the needs of the campus as a whole.

Why would I want to release a message from the Quarantine?

Sometimes, the Proofpoint Protection Server designates a message as spam even though it's a legitimate email. If you decide you want to read the message, you can release it. Releasing the message removes it from the Quarantine and delivers it to your mail box.

For example, you may be on a mailing list that sends you notices about new movies available on DVD. You want to receive these notices, but the Proofpoint Protection Server takes a conservative approach and scores these messages as spam and sends them to the Quarantine. When you look at your Digest, you will see that these are messages that you indeed want delivered to your mail box.

It is recommended that you add the sender to your safelist to prevent future messages from going to the quarantine.

What happens to my messages in the Quarantine?

If you do not release a message from the Quarantine, it will automatically be deleted after a designated period of time. So if you look at the messages in your Digest, and determine that all of them are spam, you do not need to do anything. The messages will automatically be deleted from the Quarantine.

What is a Safe Senders and Blocked Senders list?

There are two types of Safe Senders lists: the Global Safe Senders List and your personal Safe Senders List. Both are simply lists of legitimate senders of email. The email administrator controls the Global Safe Senders List, which applies to everyone in the organization. You control your personal Safe Senders List to which you can add the addresses of people, organizations, and mailing lists from which you do want to receive mail.

If a sender's address is included in the Safe Senders List, the Proofpoint Protection Server filters the message for a virus or inappropriate content, but does not filter for spam.

There are two types of Blocked Senders lists: Global Blocked Senders List and your personal Blocked Senders List. These lists contain addresses of people, organizations, and mailing lists from which you do not want to receive “junk email.” The email administrator controls the Global Blocked Senders List, which applies to everyone in the organization.

If a sender's address is included in the Blocked Senders List, the Proofpoint Protection Server filters for viruses and inappropriate content, but does not filter for spam before sending it to Blocked folder in the Quarantine.

What is a false positive?

A false positive is an email incorrectly identified as spam. If an email message is scored as spam and sent to the Quarantine, but it really is a legitimate message from a legitimate sender, you can report it as a false positive.

In the future, messages that have the same characteristics as the message you reported will not be placed in the Quarantine for containing spam.

There were some reports initially of email sent through Blackboard and various others that were being incorrectly reported as spam. The system administrators have resolved the problem and all future correspondence from Clemson should not be quarantined.

Someone did not receive my message, was it quarantined?

There are some sent messages incorrectly identified as spam that get quarantined. If the recipient has not received the message after 1 day, we recommend that you re-send the message. We have taken steps to prevent any future messages from being quarantined that originated from Clemson users.

What is a false negative?

A false negative is an email incorrectly identified as not spam. An email message that is incorrectly delivered to your mail box because it was not identified as spam can be reported as a false negative.

Spammers are very clever and are always finding ways to trick products like the Proofpoint Protection Server into delivering spam to your mailbox. Proofpoint sends frequent updates to our organization in an attempt to stay one step ahead of the spammers.
