PowerElf Anti-Spam Filter / Anti-UBE (Unsolicited Bulk Email Filter)
The PowerElf antispam server appliance easily stops viruses and spam in their tracks. Setup is done through an easy-to-use GUI interface.
Unsolicited mail messages not only slows down productivity on the server, it also wastes end-users time by forcing them to sort messages in order to find relevant emails. The PowerElf can be used as a standalone mail server or as a proxy mail server.
The PowerElf uses several different techniques to help stop spam at its entry point, long before it has a chance to travel to the end-user's
mailbox.
- The mail server receives the mail and puts it through the optional antivirus scanner to ensure that the mail passing through does not contain a virus.
- If antivirus is installed, and 2-stage mail filtering is enabled, the virus scanner will check incoming mail against a conservative online DNSRBL list. Well known spam servers are stopped at connection. This feature prevents your server from having to process very well-known spam e-mail.
- Now, mail passes through the attachment filter to scan for undesirable executable attachments. The administrator can configure and enable this feature for all types of attachments, including non-executable content, such as mp3, jpg, gif, and mpg.
- The mail message is received by the antispam engine. The engine uses it's heuristics to scan the content of the message. It can also perform a DNSRBL and bulk-mail check before assigning a "spam-rating" number to the e-mail.
- The spam rating number is determined by a rule set that calculates the likelihood that a piece of mail is legitimate or spam. The "tagging" level and "auto-delete" level are controlled and set by the administrator.
- If the "auto-delete" is enabled and the threshold is set, the server will determine whether to delete the spam or let it pass though.
- Tagged (suspected spam) and non-spam e-mail will be delivered to the recipient. Mail that is suspected to be spam will be marked accordingly.
