Sophos: E-mail Appliance and PureMessage
Spam is the most common problem that comes through email. Unwanted mail, bulk mail, and fraudulent mail are all forms of spam — and they all pose risks to the college email. Spam can gobble storage space, bandwidth, and server load, making our email system less efficient.
In July of 2005 Caldwell College began using a package called PureMessage to scan your e-mail for viruses and spam. In the Fall of 2008 we added the Sophos E-mail Appliance to give us another layer of protection. Together they scan all e-mail before it gets to your mailbox.
If your e-mail address receives any message that our filtering software considers spam the software will put it into your quarantine. You can also manage your personal quarantine by approving or blocking senders using the web site listed below. You will receive an e-mail once a week showing any new spam that has been captured in the last 7 days but you can also access this site at any time.
How to email spam, and false-positive spam samples to SophosLabs
It is preferred that you send samples as RFC-2822 attachments. Submitting in any other format can cause the loss of key message content, which may prevent SophosLabs from effectively analyzing the samples.
Email spam samples to :
• is-spam@labs.sophos.com
Email false-positive spam samples to :
• not-spam@labs.sophos.com
From Microsoft Outlook
1. Create a new email message
2. Address it to : is-spam@labs.sophos.com : not-spam@labs.sophos.com

Managing Virus Attachments:
The message below is an example of what you will get if a message that was sent to you contains a virus. It tells you who sent you the message, the name of the attachment, the name of the virus that was detected and if it was able to be disinfected or not. Most viruses that are sent by e-mail are files that were written to be a virus and there is no way of disinfecting the file. If you have any question about files that were captured as a virus please call the appropriate Help Desk.
