Junk E-mail Filter and Spam Digests Frequently Asked Questions

How does the CSU Junk E-mail/Spam filter work?

The CSU junk e-mail/spam filter is a server based anti-spam tool that detects and quarantines spam messages before they can get to your inbox. Messages are scored from 0-100. Messages that receive a score from 50-100 are considered to be spam, and will be held in quarantine before reaching your inbox.

What happens when messages are quarantined?

The scored messages are held for 14 days and then deleted. You will receive a digest or list of the quarantined messages, and have an opportunity to release any valid e-mail messages, to be sent to your inbox.

What is the CSU Junk E-mail/Spam Digest?

The junk e-mail/spam filter scores messages and moves them into a quarantined holding area before the messages reach your mailbox, and then sends a digest listing those messages it has quarantined. Our campus has set the junk e-mail/spam filter digest to be sent to you daily at 3 p.m. You can then review the digest for messages that are not spam, and release those to your inbox. If no false positive or improperly marked messages are found in your digest, then the digest itself can be deleted.

What do the options mean in the junk e-mail/spam digest?

The digest lists e-mails that have been placed in your personal quarantine.
For each of the quarantined messages listed, you have the following options:

Release: delivers the e-mail to your inbox
safe list: delivers the e-mail to your inbox and add the e-mail sender to your safe senders list. This ensures that no e-mails from that sender will be blocked in the future. Future messages from this sender will not be sent to the quarantine
Not Spam : To report messages that are not spam but are reported in the digest.

If you do nothing, these messages will be deleted for you after 14 days.

Do I need to set a spam rule in Outlook for the spam filter to work?

No, you don’t need to set a rule to filter spam, but you may want to set up a rule that moves your daily digest message to a folder in your mailbox. Doing this will keep your digests in one place for ease of reviewing and keep the digests separate from your other e-mail messages.

We have provided a tutorial to help you create a rule for moving your digest to a folder in your mail box: digest filter.

Some users find that they rarely if ever have false positives where a valid message is marked as spam. The spam filter works with great accuracy and you may want to have the digests deleted weekly from your digests folder in the same way the deleted items folder is emptied on a regular basis.

What is a spam score?

Messages identified as spam will be marked with the word "spam" followed by a numeric score, and the score will appear at the beginning of the subject line. Messages are scored from 0-100. Messages that are held in quarantine have been rated with scores from 50-100. A score of 100 is rated as certain to be spam.

This filter not only protects against current spam, but it also learns to identify new sources of spam. It is an intelligent technology, which is continually being trained to defend against new forms of spam and to predict and adapt to those new forms as they appear. Its ability to defend against spam attacks does not degrade over time.

Do quarantined messages count in my mailbox quota size?

No, quarantined messages do not count against mailbox quota size. Quarantined messages are held for 14 days on a different server, before they ever reach your account. You must manually release them from the digest, to be delivered to your mailbox. Only when a message is actually in your mailbox, is it counted in your quota size limit.

What is the safe/blocked senders List?

Your safe senders List is a list of e-mail addresses of individuals and organizations approved by you as “safe” (or not spam). This list ensures that e-mails from that sender will be delivered in the future and not filtered as spam. You can add/delete senders to the list as needed and you can always request an updated safe senders list for review.

Your blocked senders list is a list of e-mail addresses of individuals and organizations blocked by you as “not-safe.” It ensures that no e-mails from that sender will be allowed in the future, and they will be filtered as spam. You can add/delete senders as needed and you can always request an updated blocked senders list for review.
