Highlights of the release [...] - new plugins: DomainKeys (off by default), MIMEHeader: a new plugin to perform tests against header in internal MIME structure, ReplaceTags: plugin by Felix Bauer to support fuzzy text matching, WhiteListSubject: plugin added to support user whitelists by Subject header.
Finally DomainKeys support, this should help a lot in catching spam with spoofed yahoo mail addresses. Wonder how many popular sites use domain keys other than Yahoo and Google. Need to figure out how to add domain keys to my http://shankerbalan.net/ domain too. The weekend is almost here… 🙂
