OIT's spam filtering system works by scanning incoming email for spam, phishing and malware before it gets delivered to your email Inbox. High-confidence phish and malware are dropped or quarantined prior to delivery, while other messages identified as spam are sent to your Junk Email folder. OIT’s multi-application approach helps prevent attempts to acquire user credentials by malicious parties.

If the message is suspect, the spam filter will simply place the item in Junk E-Mail. You may occasionally receive email notification about particularly suspect or malicious messages.

Because SMU uses multiple applications, you may see more than one “Junk Email” folder, including one named “Junk E-mail” (with a hyphen). The Armorblox application adds a prominent, informative banner to messages detected as spam. The Microsoft Defender application monitors both inbound messages and messages in the Inbox for spam, including zero-day exploits. If a message is identified as phish or malware post-delivery, it will be removed from your inbox.
