Could you please elaborate on these "legal issues"? 

http://cr.yp.to/qmail/dist.html  says

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 <var-qmail.html> 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 
<../compatibility.html> 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.
