Spam Filter and AntiVirus Solution to be Implemented
Posted Wednesday, March 19, 2003 by jeremy
|In order to address customer requests as well as improve network security, MOREnet is prepared to deploy the RAV (Reliable Anti-Virus) spam and anti-virus engine for managed customer e-mail during the week of March 24-28, 2003.
- Spam will be marked, but not rejected. MOREnet System Administration has determined through previous experiments and attending the recent Spam Conference at MIT that the cost of blocking legitimate e-mail outweighs the advantage of rejecting spam.
- Customers can use their e-mail client's filtering feature to move e-mail marked as spam into a separate folder (e.g., Trash). However, please note that e-mail may occasionally be marked incorrectly as spam -- a false positive. Please check the subject and sender lines of e-mail marked as spam prior to final erasure.
- Viruses and other malware can infect a system by means other than e-mail. Customers should have local file server and desktop anti-virus tools in place and should keep the virus signature file up to date.
- The anti-virus scanner discards well-known viruses (e.g., Klez, etc.) outright, with no notice to the sender or recipient, though the discard is logged.
- The scanner attempts to clean and deliver e-mail infected with less common viruses. If cleaning fails, the e-mail is discarded (and the discard is logged).
For the time being, only incoming e-mail will be scanned for viruses and spam. Another announcement will be posted when scanning of outgoing mail begins.
