Welcome to Spam Busters
Quick Tip: Is it blocked?
Use the Block Status Check tool to find out if a particular IP address, e-mail address, or domain is currently blocked at U-M. If it is blocked, mail coming from it will not be accepted for delivery.
Departmental Anti-Spam Services
Many U-M units provide their own e-mail and anti-spam services. Please check with your department's information technology help desk to find out what is available to you.
