In their own words
Apache SpamAssassin
Apache SpamAssassin is free, open-source software that classifies email to help system administrators block unsolicited bulk messages. It runs on a server to filter mail before it reaches a mailbox. Detection combines header and text analysis, Bayesian filtering, DNS blocklists, collaborative filtering databases, and local and network tests. Its scoring framework and plugins add heuristic and statistical checks. Tests and configuration are stored as plain text, so administrators can adjust settings and add rules. The Mail::SpamAssassin API can be integrated with systems such as procmail, sendmail, Postfix, and qmail. The core distribution includes command-line filtering tools and Perl modules for use in other products. The downloads page lists version 4.0.2 as the released version. Official releases are signed, with GPG signatures and SHA-256 and SHA-512 checksum links for downloads. Users can ask questions on the mailing list; developers and PMC members answer as time permits.
Mailprotector
Mailprotector makes email security and management products exclusively for managed service providers. Shield combines a secure email gateway with an API integration for Microsoft 365 environments; the company says Google Workspace support is on the horizon. CloudFilter filters email where customers control MX records, including Microsoft 365, Google Workspace, on-premises servers, hosted environments and POP/IMAP. Bracket encrypts messages when a subject contains square brackets, without requiring apps, plugins or passwords from senders or recipients. It uses AES-256, and its one-time sign-in links expire after 15 minutes or become invalid if opened from another device. SecureStore captures messages going forward and has a seven-year default retention period, which can be adjusted. Mailprotector states that it holds the HIPAA Seal of Compliance from Compliancy Group and is SOC 2 Type 2 certified. ConnectWise, Autotask and Gradient integrations support licensing or service-count synchronization and billing workflows, and are free. Radar is a free email security check; current product pricing is available from an account manager.
