There was a license of sorts on DJB's web site:

http://web.archive.org/web/20000517200720/cr.yp.to/qmail/dist.html

    If you want to distribute modified versions of qmail (including
    ports, no matter how minor the changes are) you'll have to get my
    approval. This does not mean approval of your distribution method,
    your intentions, your e-mail address, your haircut, or any other
    irrelevant information. It means a detailed review of the exact
    package that you want to distribute.

    Exception: You are permitted to distribute a precompiled var-qmail
    package if (1) installing the package produces exactly the same
    /var/qmail hierarchy as a user would obtain by downloading,
    compiling, and installing qmail-1.03.tar.gz,
    fastforward-0.51.tar.gz, and dot-forward-0.71.tar.gz; (2) the
    package behaves correctly, i.e., the same way as normal
    qmail+fastforward+dot-forward installations on all other systems;
    and (3) the package's creator warrants that he has made a good-faith
    attempt to ensure that the package behaves correctly. It is not
    acceptable to have qmail working differently on different machines;
    any variation is a bug. If there's something about a system
    (compiler, libraries, kernel, hardware, whatever) that changes
    qmail's behavior, then that platform is not supported, and you are
    not permitted to distribute binaries.

There's a copyright statement in the README file in the source tarball,
but no license; not even a reference to the web site.  The tarball
hasn't changed since 1998, because qmail is perfect and absolutely
bug-free, as documented here:
