Spam Filtering (Filtering of Unsolicited Email)

A new spam filter has been activated to replace SpamAssassin. While the new spam filter won't eliminate 100% of spam, you should receive less spam once it has had time to adjust to campus email traffic.

From time to time, the spam filter may incorrectly place an email in your Junk Mail folder. To ensure you receive all important email, it is advisable to monitor your Junk Mail folder on a regular basis.

The following questions have come up most frequently regarding the new spam filter:

How do I keep "safe" email from coming into my Junk Mail folder?
For email incorrectly marked as Junk Mail, copy and paste the sender into the Safe Senders list using the steps below:

1. Log in to your email.
2. Click Options from the left side menu.
3. Scroll down to the Privacy and Junk E-mail Prevention section and click Manage Junk E-mail Lists.
4. Click Add next to the Safe Senders dialog box.
5. Type or paste the copied email address you wish to be marked as “safe.”
6. After 10-15 minutes, the server will be updated to recognize all future mail from that sender as "safe."

This solution also applies to customers using email programs other than Outlook.


Mail not delivered to Inbox or Junk Mail folders
Some customers have expressed concern that mail may not be getting through to them. In this case, mail may be blocked from coming into our mail server and never has the opportunity to get sorted as safe or junk email.

Off-campus senders whose emails addressed to mst.edu are blocked will be sent an automated message informing who to contact for assistance.

If you feel messages simply aren't getting through to your Inbox or Junk Mail folders, please contact postmaster@missouri.edu with your email address, the senders’ email address, and the approximate time the message was sent (if you know this information) or contact the IT Help Desk at 573-341-4357 (HELP).
