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.Hourly Mail Statistics

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
- 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

- 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
- 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
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.
