* Most research estimates 88-91% of the mail traffic on the Internet is SPAM.

* So far this year, 81% of all mail sent to UIS is SPAM.

* For people in the U.S., the peak time for receiving SPAM is between 9am and 10am.

* Every time we whitelist an organization, we are bypassing all scanning of mail originating from their network, and we are trusting them to ensure the security of the machines on their network.

* In addition to Barracuda’s own scanning systems, UIS runs every inbound message through Spamhaus<http://www.spamhaus.org/> to check it against their blacklists.
