CleanMail Server is a Security & Privacy::Anti-Spam & Anti-Spy Tools software developed by byteplant GmbH. After our trial and test, the software was found to be official, secure and free. Here is the official description for CleanMail Server: CleanMail is a complete Anti-Spam/Anti-Virus solution (SMTP/POP3) that works with any mail server like Microsoft Exchange, Microsoft Small Business Server (SBS), Lotus Notes/Domino or IMail. CleanMail includes a comprehensive set of filters, including an attachment blocker, remote blacklist filter (DNSBL), anti-virus filter and a complete Windows build of the award-winning, open-source SpamAssassin filter. CleanMail integrates the Clam Anti-Virus package and additionally supports all popular virus checkers to protect you against all kinds of email-borne virus attacks. With CleanMail you have online access to view real-time statistics charts and reports using a web browser, or using the CleanMail Admin application. Data available online includes spam statistics, mail logs (a listing of mails received, including subject, sender and recipient address), and a ranking of spam hosts (hosts submitting spam mails ie. in the last 24 hours). Additional features include traffic limiting (to protect your mail service from directory harvest attacks and mail backscatter), mail archiving (to quarantine dubious messages, or to meet legal or regulatory obligations), and email notification (to alert about conditions that need administrator attention). CleanMail's highly versatile filter pipeline provides an open interface that allows integrating custom mail filters, such as tools for email classification, automated mail processing, or server-based email encryption. CleanMail is available as freeware for personal and non-commercial use. A range of commercial licenses is available, offering exceptional value at low prices. The purchase of a license includes maintenance and updates for 12 months. Renewal licenses are available at a discount. Communities or non-profit organizations please inquire for special discounts.

CleanMail accepts incoming emails via SMTP or POP3 and scans them, using the award-winning SpamAssassin? engine.

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 spam 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:
  • Email Header Analysis:
    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.
  • Keyword Checking and Text Analysis:
    The mail body is scanned for typical spam mail content, such as spam keywords, capitalized letters, or invitations to buy or click something.
  • Bayesian Spam Filtering:
    Bayes filtering statistically calculates the probability that an inbound message is spam. Spam mails can be learned, so that similar mails are more likely to be identified as spam in the future.
  • Realtime DNS Blacklist (DNSBL, RBL) Checking:
    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.
  • Multiple SURBL (Spam URI Realtime Blocklist) Checking:
    Spammers want you to click on hyperlinks referring to their sites, so a lookup in a database of known spam-advertised 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 (Sender Policy Framework) Support:
    SPF is an emerging standard to detect forged "From" addresses in emails.
  • Automatic Whitelist Management:
    SpamAssassin's Auto-Whitelist (AWL) tracks scores of regular correspondents to automatically identify legitimate sender addresses.
  • White and Black Lists:
    Whitelists and blacklists can be used to configure which email addresses are permitted or denied.

The result of all these tests is added up to form a spam score. A message is considered spam if the score exceeds a configurable threshold.

In the typical configuration, the subject of mail identified as spam is modified to flag it as spam mail, and a SpamAssassin? report is added to the message. Now it is up to your mail server (or client) software to decide what to do. You can delete spam mails, or move spam mails to a spam folder, or leave the decision what to do with spam mails to your users.
