Mail Scanning and Filtering

Email Scanning at the network gateway gives you the power to control what enters or leaves via email.

As email becomes the most important channel for Universities communication, scanning of message traffic is increasingly recognized as a necessary component of network protection. Common goals of email scanning are to block Spam, to stop viruses and other threats, and to ensure that email usage meets the organization's Acceptable Use Policy.

All email sent from, and received by the DWU mail server is scanned for virus and unacceptable attachments.

Any email message found that matches a scanning rule is deleted by the mail server, or may have the attachment removed.

Some common examples of email attachments that will be blocked:

attachments with more than one file extension-(example assignment.friday.doc)
attachments that are executable, or system files-(example screensaver.scr or install.exe)
email with embedded html executable code
email attachments with current virus definitions
