About IronPort AntiSpam
ITS implements a centralized email security method from Cisco called Ironport AntiSpam that scans all incoming email for spam before the messages are delivered to the user's inbox. IronPort detects and drops spam if the email meets the specific criteria defined by the antispam filters. IronPort's spam filters are extremely accurate; the percentage of legitimate email messages that are misidentified as spam--known as the false-positive rate--is an extremely low .001%.
ITS eliminates incoming email tagged as spam by the IronPort before it reaches the user's inbox.
Reporting Missed Spam
As with most spam control technologies, the IronPort is not 100% accurate. ITS would like to know about your experiences with missed spam so that we can work with Cisco to improve the antispam engine.
To report messages that were not properly tagged by the system, please see the Reporting Missed Spam page.
