IndiMail 1.6 Includes Greylisting and BATV
IndiMail, an email solution made of open source components, now includes greylisting spam filtering in version 1.6.
The IndiMail application unites among things the QMail SMTP server, Courier IMAP/POP3 server, Bogofilter Bayesian spam filter, Clam antivirus and Fetchmail. Version 1.6 includes Greydaemon, a greylisting package that reduces spam in the SMTP session (see a whitepaper on greylisting).
IndiMail supports Bounce Address Tag Validation (BATV), a mechanism for detecting invalid bounce addresses. IndiMail developers also fixed a vulnerability in Fetchmail (CVE-2009-2666).
IndiMail 1.6 is available as Debian and RPM packages and a source code tarball for download at SourceForge. The components are under free licensing such as GPL.
