SQLgrey Postfix greylisting service

File Release Notes and Changelog

Release Name: 1.4.0

Notes: New features and a SQL injection fix.

---

Changes: - whitelisting is now database independant, it can use regexps and wildcards for FQDNs, and whitelist single IP addresses or class C networks. The whitelist can be changed without restarting SQLgrey. - 3 different greylisting algorithms (greylisting on the class C network when it can be guessed to not be a home-user IP is now the default). - automatic conversion of SQL schema to new format. - a fix for a SQL injection that was missed earlier is included.
