Crackdown on university junk email ANU IT Services has instituted blocks on known nuisance and mass email posting sites in response to requests to address the problem of "junk" email. The move is designed to free reduce time taken reading and deleting unwanted mail. IT Services said the practice of sending out mass (junk) email, "Spamming", is widespread and gaining momentum as the popularity of the Internet grows. "The University's email gateway, anugpo, has over 5,000 users, receives between 20,000 and 50,000 messages per day, and forwards these to about twice as many recipients, on average. About 30 per cent of all messages arriving at the University through anugpo are rejected because of invalid source addresses (eg. santa@north.pole)," an IT spoesperson said. "It is not possible to entirely block junk email at anugpo because new address sites are constantly being established. For users, the best course of action is to look at the subject line and the sender, or the first one or two lines of the text of the message. It should quickly become obvious if the message is relevant to you - and if it is not then delete it."
