Greylite
Greylite is a SPAM filter with exceptional effectiveness and without false positives. It combines natively with qmail and works as a proxy for any SMTP server. It implements a modified greylisting algorithm that improves the filtering effectiveness and minimizes the delay drawbacks associated with the standard greylisting algorithm. It is self-contained because it uses SQLite, and is easy to setup and maintain, small, and fast.

Recent releases

- 17 Apr 2008 09:21
Changes: Plug-ins are supported for databases. Support for SQLite (default) and PostgreSQL are included. Insertion of a newline character to end the recipient information in the database was fixed.

Changes: The "354 go ahead (in reply to RCPT TO command)" bug was fixed when responding to non-suspicious clients at the second delivery attempt.
