ok, so what's wrong with software that come with no license but a redistribution restriction to a certain way.
If software has no license then nobody except its writer is allowed to do _anything_ with it! No copying, distribution or even use is legal without some kind of license.
Oh really? Then I guess Yahoo! and many others are just fools waiting to be sued by making use of qmail.
1) You can do something with it without a license. M$ uses licenses to prevent you from doing just that. The GPL puts another twist to it. You can make changes as much as you like but the day you distribute the software with your changes to a third party, that third party gets to the source code or you don't distribute the modified software.
2) As for copying/redistribution/use, you don't need a license to be able to do any of that. In qmail's case, you are free to use the software, modify it but not to redistribute it anyway you like since DJB wants to keep control of that.
