NoSpamToday! for Workstations blocks spam before it gets to your email client. It works by accepting POP3 connections on port 110 of your computer's loopback interface, and forwarding all requests to your ISP's POP3 server.
SpamAssassin combines the most effective and advanced anti spam technologies into one powerful solution that accurately determines if a message is or is not spam. It uses a comprehensive list of heuristic rules and checks to score messages.
This filtering is completely automated, and spam-scoring thresholds are customizable. It also includes Bayesian filtering and offers many additional features, such as complete spam message reporting, header reporting and much more.
SpamAssassin uses the following tests and techniques to identify spam:
The mail headers are scanned for some small inconsistencies that can give away forgeries: A mail date in the past or in the future, forged message IDs, and the like.
The mail body is scanned for typical spam mail content, such as spam keywords, capitalized letters, or invitations to buy or click something.
Bayesian filtering statistically calculates the probability that an inbound message is spam. Spam mails can be trained, so that similar mails are more likely to be identified as spam in the future.
Queries to DNSBL servers are used, e.g. to see if a mail has been submitted from a known open mail relay or notorious spam sender.
Spammers want you to click on hyperlinks referring to their sites, so a lookup in a database of known spamadvertised sites has proven to be highly effective in identifying spam mails. Similar to Realtime DNS Blacklists, SURBL (Spam URI Realtime Block Lists) checks will block messages that contain URIs in the message body that link to known spam hosts.
SPF is an emerging standard to detect forged "From" addresses in emails.
SpamAssassin's Auto-Whitelist (AWL) tracks scores of regular correspondents to automatically identify legitimate sender addresses.
White and Black lists can be used to configure which email addresses are permitted or denied.
NoSpamToday! has an integrated attachment blocker, and has built-in support for many third-party virus checkers, such as Clam AV, F-Prot Anti Virus, or McAfee VirusScan just to name a few.
Most worms and viruses are spread by attachments. Getting rid of messages containing potentially malicious attachments before even starting virus checkers or spam filters can be very helpful to reduce system load.
NoSpamToday! can be configured to run a third party virus checker before a mail is accepted. Virus mails are rejected and deleted.
Every virus checker that offers a command line interface can be integrated into NoSpamToday!.
