Spam

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.

Spam Statistics

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.
