Spam is the email equivalent of the junk mail that ends up in your letterbox. Spammers (people who send spam) send vast amounts of spam to every email address they can get their hands on. Unfortunately, there is not an equivalent of a ‘No Circulars’ sign for email, so we have special filters on our mail server which attempt to identify spam emails.
If you see an email with ***SPAM*** at the beginning of the subject line it means that we have identified it as spam.
