Here are some of the primary algorithms SpamShark employs to block SPAM and Viruses:
Blacklisting of Websites and Domains:
Webhero maintains an up to date list of the largest and most aggressive known spammers. This list is maintained by both Webhero and other anti-spam groups.
Keyword Scanning of Emails:
Scanning methods include a scoring system such that emails are scored based on a number of criteria. If the score is above a threshold, then that email is flagged as spam.
Rate Controls:
Utilized to stop denial of service attacks as well as dictionary based spam attacks.
Checksum Technology:
We monitor the number of times a particular message has appeared on the Internet. If a message has appeared over a certain number of times, it is categorized as known spam.
Message Authenticity Checking:
Several algorithms are utilized to verify the authenticity of a message. Some of these are simple checks to verify that the “from address” is authentic.
File Attachment Blocking:
Built in tools to block harmful scripts and viruses sent via file attachment in emails.
