Hi Joy,
The new script can be found on this link;
Make sure that you add the -i flags on all grep commands
so that it will not miss uppercase characters.
http://www.ornl.gov/its/archives/mailing-lists/qmail/2001/03/msg01041.html
The script includes the instructions on how to use it. Please read it
carefully. You cannot use the script like what you are doing. e.g. using
it
together with condredirect. Just read the instructions.
If you want to redirect the mail just edit the checkhab script. it is
document in there.
cheers.
