As you say, it is the _child_ exim process executing my script, so the
change may be/is really relevant to my problem. It would be very
strange if changing the handling of SIGPIPE in the _parent_ process
influenced the execution of the script, wouldn't it?

Hmmm, if my script assumes any broken behaviour, than by accident.

Really, there is no advanced stuff in this script. The only part
dealing with I/O is:
If there is anything wrong with the script, I'm eager to hearing it.
Do I really have to explicitly change SIGPIPE handling in any shell
script that is called from within exim?
