qmail is now Public Domain
qmail in some circles has had a bad rap because of its overly restrictive licensing policies and possibly its punctuation problem. Overly restrictive? Yes, it could only be distributed in source form. In order to use it you must compile it yourself. You could not distribute it compiled form and you couldn’t distribute patched sources for qmail.
Daniel J. Berstein recently made a public announcement that qmail, and the rest of what he has written and proviced to the public, is now placed in the Public Domain.
Watching the video I get the feeling that it is a reactive protest to other freely distributive licenses such as BSD and the GPL varriants. Whatever the reason, this means that all Linux projects like CentOS and Fedora can now distribute qmail without any licensing problems.
Now projects like QmailToaster and Dag Wieer’s RPM repository can now distribute compiled rpms instead of src.rpms.
