ulimit changes the limit in the current shell *and* its descendents. So
just write a wrapper that calls ulimit and then executes your program in
the background.
For example, in /var/qmail/rc:
#/bin/sh
ulimit -n 1024
exec ... qmail-start ...
Note that you must be able to also change this limit globally and
permanently either at boot time or on the fly. This depends on the OS you use.
