probably because you did not restart qmail *using the shell with the modified
you can't change ulimits and expect programs that are already loaded to
be affected in any way, it is bash specific.
so, change ulimits, stop qmail, restart qmail, log out of shell. or
change qmail's init script to set the ulimits for you BEFORE it changes
uid to non root.
