Personal Antispam
Personal Antispam is a spam-filtering utility for macOS designed to protect email accounts from unsolicited messages. It works as a plugin or filter for popular email clients including Mail, Entourage, Outlook and other IMAP-based email applications. The app uses machine-learning and rules-based filtering to identify and quarantine spam, reducing the amount of unwanted mail that reaches users' inboxes. It has been marketed as a lightweight alternative to built-in email spam filters for users who want more granular control or additional filtering layers.
AI Recommendation
1 suggestionPersonal Antispam appears to have been abandoned — the most recent publicly available information dates to 2012, and there is no evidence of native Apple Silicon support or active development from the vendor in recent years. The app was originally built by Intego, a security software company, but development appears to have ceased well over a decade ago. Because there is no native Apple Silicon build and the project is no longer maintained, this app will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). Modern versions of macOS Mail include robust built-in spam filtering that has improved significantly since Personal Antispam's heyday, and most email providers (Gmail, iCloud, Outlook.com, etc.) now perform server-side spam detection as well. If you are currently using Personal Antispam, you can confidently rely on your email client's native filters going forward — no third-party antispam tool is necessary on modern macOS. If you prefer an extra layer of protection, consider switching to a modern security suite like Intego's own current offerings (Mac Internet Security X9 or later) or a dedicated email security application with active native Apple Silicon support.
