DNSSEC.
Vapour. Doesn't exist at this time. (for use on the Internet) Will be implemented in djbdns when the infrastructure to support it is set up.
That's odd... since .mil is rolling it out, and I know other people using it.
Plus DJB's license sucks ass, it's almost impossible for vendors to ship his software, and for developers to work on it,
This is something I can understand. For distributors, it *is* nearly impossible to ship, and modifying and redistributing isn't allowed. Distributing patches however, is. This means you'll (as a sysadmin) will have to download and install djb-ware yourself. I don't have a problem with that, personally.
That's real useful for end users :P. Wietse (postfix guy) was smart, 100% compatible sendmail replacement, both in functionality and license. Qmail is NOT. Neither is djbdns a drop in replacement for Bind. Hence only a minor percentage of people will make the effort to use it.
qmail might indeed be getting a bit old, but there are many improvements available. (but I thought we were discussing BIND here :-) )
The same thing will happen to djbdns ultimatwly, since the only person that really does any work on DJB's software is DJB. -Kurt
