For those with a unr.edu e-mail address, the University E-mail system works very hard to stop spam (unwanted e-mails) from reaching your inbox (via a system called Proofpoint). Most of the time, the spam is obvious and easily caught (unless you really wanted that cheap "Rolex" watch). However, occasionally, an unwanted e-mail will make it into your inbox because it has cleverly disguised itself as looking legitimate. Luckily, there are tell-tale signs that can help you to identify whether an e-mail is legitimate or not.
To ensure that a genuine e-mail is not entirely blocked by the spam protection system, your unr.edu e-mail account should occasionally receive an e-mail containing a list of all the messages that have been blocked by Proofpoint: the End User Digest. This list displays the e-mail address that sent the message, the subject, and a score out of 100 for how spam-y the system thought the e-mail was (100 is complete certainty that the e-mail is not legitimate).
The links to the left of each message allow you to View the message in a safe environment, Release the message from Proofpoint so that it gets delivered to your inbox, Safelist the sender so that their e-mails do not get blocked in the future, and mark the e-mail as Not Spam so that Proofpoint can improve its artificial intelligence on what is and isn't an unwanted message (this will also move the e-mail into your inbox).
There are several steps you can take to avoid getting bombarded with unwanted messages.
