We recently installed a new hardware firewall called a "Barracuda" to stop the vast majority of spam that's comming into this office. This will stop the malicious and vulger emails.
Like all spam filters, it is constantly learing what is spam and what isn't. The Barracuda is in the middle of this learning process right now, so some good emails will be blocked by it at first.
Please inform Christina in the SG with any email addresses that are being blocked by the new filter. She will start a simple spreadsheet of these email addresses so that they can be given to Rob to add to the "safe sender" list.
