Does this look right? ("Tainted filename" fix)
A recent cPanel update left me facing the dreaded "Tainted filename for
search" issue.

My system automatically generates a custom aliases file via cron. This was
implemented more than 10 years ago. It required two modifications to the
Exim config. Those failed after the update. I was able to put a manual
workaround in place but would like to find a workable replacement for the
original modifications.

After reading the documentation and past posts to this list, among other
sources, I've come up with the following. But my understanding of this is
still pretty thin. I'd feel better if someone a lot smarter than me could
look at it before I try to install it.

Thanks in advance for any comments or suggestions.
