Thanks for the info. That did the trick. I don't see any real security
risk involved in the action, but I will discuss with other system
administrators before global implementation.
At least you are trying to prevent users from loggin on the server. And
this is eluded by procmails ability to fork shells and other programs.
With a little script like the one below your users can cause serious
problems for the server:
while : ; do "$0" & ; done
Eventually there will be no longer any free process handles - at least for
users. root should have no problems though.
