Barracuda spam appliances are our front line of defense against spam. The mail that passes through the Barracuda filtering then goes through Exchange Internet Messaging filters and McAfee's Groupshield. The charts below show current statistics from the Barracuda. In addition to the Barracuda blocked messages, another 3000 or so are blocked daily by the IMF and Groupshield.

The statistic charts can only be viewed from campus computers.

McAfee Tips on Spam
· Never respond to spam. If you reply, even to request removing your e-mail address from the mailing list, you are confirming that your e-mail address is valid and the spam has been successfully delivered to your inbox, not filtered by a spam filter, that you opened the message, read the contents, and responded to the spammer. Lists of confirmed e-mail addresses are more valuable to spammers than unconfirmed lists, and they are frequently bought and sold by spammers.
· Do not open spam messages wherever possible. Frequently spam messages include "Web beacons" enabling the spammer to determine how many, or which e-mail addresses have received and opened the message. Or use an e-mail client that does not automatically load remote graphic images, such as the most recent versions of Microsoft® Outlook® and Mozilla Thunderbird.
· Do not click on the links in spam messages, including unsubscribe links. These frequently contain a code that identifies the e-mail address of the recipient, and can confirm the spam has been delivered and that you responded.
· Never buy any goods from spammers. The spammers rely on very small percentages of people responding to spam and buying goods. If spamming becomes unprofitable and takes lots of effort for little return, spammers have less incentive to continue spamming. Would you risk giving your credit card details to an unknown, unreputable source?
· Make sure that your anti-virus software is up to date. Many viruses and Trojans scan the hard disk for e-mail addresses to send spam and viruses. Avoid spamming your colleagues by keeping your anti-virus software up to date.
· Do not respond to e-mail requests to validate or confirm any of your account details. Your bank, credit card company, eBay, Paypal, etc., already have your account details, so would not need you to validate them. If you are unsure if a request for personal information from a company is legitimate, contact the company directly or type the Web site URL directly into your browser. Do not click on the links in the e-mail, as they may be fake links to phishing Web sites.
· Do not click on unusual links. Confirm the sender did send the e-mail if it looks suspicious.
· Never give out your login details to anyone.
