Postfix greylisting service

'SQLgrey' is a Postfix greylisting policy service with auto-whitelisting that uses an SQL database as its storage backend. It is based on postgrey, refining auto-whitelisting and storing whitelists and connection attempts in a database. Greylisting stops 50 to 90 % junk mails (spam and virus) before they reach your Postfix server, saving bandwidth, user time and CPU time.
