SQLgrey is a Postfix greylisting policy service with auto- whitelisting and an SQL database as storage backend.
It is based on postgrey, refining auto-whitelisting and storing whitelists and connection attempts in a database. Its goal is reducing the amount of spam reaching user mailboxes.
Here are some key features of "SQLgrey":
SQLgrey can withstand a database crash (grey-listing is automatically switched off)
3 grey-listing algorithms to choose from
Support for file-based IP and FQDN whitelists
Support for fetching up-to-date whitelists from a repository
Can mail the admin when the database is unavailable
Auto-whitelists now understand SRS (SPF-aware mail forwarding)
OPTIN / OPTOUT support
Fine log controls
Net::Server::Multiplex (at least 0.87 is recommended, stability issues have been reported with earlier versions),
SQLite, MySQL or PostgreSQL (PostgreSQL is recommended).
What's New in This Release:
A bugfix for a rare multiple instances race condition that permanently blocked some messages.
