I guess this is it Smilie WARNING: There is no error checking at all!

Code:
#!/bin/bash

ufile=$1 #user file name
ulf=$2 #user line from
ult=$3 #user line to

ifile=$4 #item file name
ilf=$5 #item line from
ilt=$6 #item line to

for user in `awk -vULF=$ulf -vULT=$ult 'NR>=ULF && NR<=ULT' $ufile` ; do
 for item in `awk -vILF=$ilf -vILT=$ilt 'NR>=ILF && NR<=ILT' $ifile` ; do
  echo $user @ $item
 done
done

Demonstration:
Code:
$ for i in {1..100}; do echo user$i >>userlist; done
$ for i in {1..100}; do echo item$i >>itemlist; done
$
$ ./script.sh userlist 23 30 itemlist 60 65

NAME
installsieve - user utility for managing sieve scripts SYNOPSIS
installsieve DESCRIPTION
installsieve is a utility that allows users to manage their sieve scripts kept on the server. OPTIONS
-v <name> View script with the given name. The script if retrieved sucessfully is output to standard output. -l List all of the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active script. -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services. -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten. Upon sucessfully putting the script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since sieve names may not contain a '.'. -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option.. -d <name> Delete the sieve script on the server with <name>. -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen. -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already exists it is overwritten. -u <user> Userid/Authname to use for authentication; by default, the current user. CMU
