Ok now next problem that I ran into in trying to get qmail running on the distrubution is that checkpassword-0.90 doesnt want to compile and looking on the web there is 1 arabic website explaining how to get around this which I cant understand but with again more pain I have finally cracked it.
In the source directory of checkpassword you will need to change the error.h file to include errno.h just after the line extern int errno like so...
extern int errno;
#include <errno.h>
then recompile and everything should work.
