Altospam: Open Source Spam Filtering Software
Open source spam filtering software using rules, Bayesian filtering, blacklists, and whitelists to accurately detect and block email spam.
What is Altospam?
Altospam is an open source email spam filter software developed as an alternative to commercial solutions like SpamAssassin or SpamPal. It aims to provide accurate spam detection combined with ease of use and flexibility.
The software utilizes a variety of anti-spam techniques including DNS blocklists, Bayesian filtering, heuristic rules, reverse DNS lookups, greylisting and more. These work together to analyze email content and metadata to determine if a message is spam.
A major benefit of Altospam is customizability - users can tweak settings like Bayesian statistical analysis, add custom rules, whitelist senders, and more to improve accuracy over time. Integration with other mail services is simple via the Milter protocol.
As an open source solution, Altospam provides a no-cost alternative for personal use, small businesses, schools and nonprofit organizations. It can run on Linux, BSD, Solaris and macOS platforms. The codebase is actively maintained by a community of developers and users.
Overall, Altospam presents a compelling spam filtering option. Non-technical users can get started quickly using default settings while more advanced ones can deep-dive to optimize performance. The availability of community support also makes it easier to operate for most use cases.
