Ubuntu Linux SPF Checking

Ubuntu Linux 7.04 (Feisty Fawn) Released With Support For SPF Checking

The newest release of the popular Ubuntu Linux distribution includes Perl and Python SPF libraries that are compliant with RFC 4408 and the SPF test suite. Also included are associated Postfix policy servers. Postfix is the preferred mail server for Ubuntu. This is mentioned in the New Feature Tour (in the mail server section).

About the SPF Project

The SPF Project was founded in 2003 by Meng Weng Wong and other dedicated internet technologists to act against the increasing levels of e-mail sender address forgery by spammers, imposters, and computer viruses.

The project has developed the sender authentication technology called Sender Policy Framework, which aims to fix various ambiguities in the standards underlying the e-mail system that have essentially remained unchanged since their inception in 1982. SPF allows domain owners to define who may and may not send mail using their domain names.
