Here's the text of the campus-wide message:
CNS has been evaluating and testing the Barracuda Spam Firewall as a possible replacement for our current spam filter, and had planned to switch to it in the near future. This Friday, sending and receiving email off-campus was broken for several hours, due to our current spam filtering systemís licence expiring prematurely. When the license was extended, we had significant issues bringing the system back online. While email messages were only delayed and not lost, we consider this to be a serious problem. Due to this and other ongoing concerns we have decided to advance the replacement cycle of the spam filter and complete the upgrade today.
The new system behaves slightly differently than the old one, and we believe it will do a better job of filtering unwanted messages. You will still receive daily quarantine messages. The reports have the option to release the message, release and add sender to your "whitelist" or delete the message from quarantine. http://spam.drew.edu will still be available to examine your quarantine at any time, and allows you to configure some personal preferences as well.
While these interfaces may look different we believe they should be as easy if not easier to use than the previous system. You will also notice far fewer messages in your quarantine, which should make it simpler to find legitimate emails that were blocked. This is due to the additional filtering methods the Barracuda uses to block email from known undesirable origins. Also, current deny/allow from the old system will not be on the new system; we expect to be able to migrate them for you shortly.
We've been satisfied with the Barracuda product so far, and as our renewal for the old product was coming up, the timing was right to examine other products. We expect it to be more reliable than our old solution.
You will receive one more quarantine report from the old server, and clicking on the actions in that message will still work appropriately. In addition, the old spam filter will be available at http://oldspam.drew.edu/ for at least one week in case you need to review messages it has captured.
Please use this thread for questions, problems, and what we hope is positive feedback.
