Spam Firewall
Information Technology Services has implemented the Barracuda Networks Spam Firewall to control the massive amounts of spam targeting Trinity Valley Community College. The Barracuda Spam Firewall is an integrated hardware and software solution that is used to protect TVCC email from spam, viruses, spoofing, phishing, spyware attachments, and denial of service attacks.
What is a Spam Firewall and how does it work?
Answer
Barracuda Spam Firewall is an integrated hardware and software solution that is used to protect TVCC email from spam, virus, spoofing, phishing, spyware attachments, and denial of service attacks. All email before it is sent to a users inbox is sent through the Barracuda Spam Firewall to be processed. Addresses that appear on your Whitelist are automatically sent to your inbox while addresses on your Blacklist are deleted immediately. The remaining email is scored (evaluated as to the likelihood that it is spam), and handled according to your configuration settings. It takes about 200 spam and non-spam messages before the Bayesian analysis starts to recognize and block spam. (See definition list '> definition list for Bayesian.)

What file attachment extensions are blocked by IT Services?
Answer
IT Services blocks several file extensions for security reasons. Email containing certain files could be harmful to your computer or the college network. To prevent an individual from transmitting an email containing a malicous program we block the following file extensions.
ad | ade | adp | asp | bas | bat | chm | cmd |
com | cpl | crt | eml | exe | hlp | hta | inf |
ins | isp | js | jse | lnk | mdb | mde | msc |
msi | msp | mst | pif | pod | reg | scr | sct |
shb | vb | vbe | vbs | vsd | vss | vst | wsw |
wsf | wsh | zip |
Does this mean that I cannot send a file with the zip extension?
No. You can send a zipped file. You need to simply rename the extension to zit. For example if you have a file called documents.zip rename the file extension so the file is documents.zit. This will allow the email with the file to be delivered. Just remember to have the receipiant to rename the file back to documents.zip before he/she unzips it.
